Mapping the 3D Geometry of Active Faults in Southern California

Abstract Accurate assessment of the seismic hazard in southern California requires an accurate and complete description of the active faults in three dimensions. Dynamic rupture behavior, realistic rupture scenarios, fault segmentation, and the accurate prediction of fault interactions and strong ground motion all strongly depend on the location, sense of slip, and 3D geometry of these active fault surfaces. Comprehensive and improved catalogs of relocated earthquakes for southern California are now available for detailed analysis. These catalogs comprise over 500,000 revised earthquake hypocenters, and nearly 200,000 well-determined earthquake focal mechanisms since 1981. These extensive catalogs need to be carefully examined and analyzed, not only for the accuracy and resolution of the earthquake hypocenters, but also for kinematic consistency of the spatial pattern of fault slip and the orientation of 3D fault surfaces at seismogenic depths. The San Andreas fault system in southern California has a high probability of generating a major damaging earthquake. How big, when and where such an event will occur appears to depend on subtle, second-order variations in stress, strength and fault geometry, such as fault bends, offsets, changes in fault dip, or other fault discontinuities that seem to control fault segmentation and rupture behavior. As demonstrated by recent large earthquakes, rupture along major through-going faults in southern California can be quite complex, and strongly affected by both local fault geometry and the interaction with adjacent secondary structures, such as sub-parallel fault strands, left-lateral conjugate cross faults, tear faults, and low-angle basal detachments. Identification of these features, especially at seismogenic depths, often depends on careful kinematic analysis of the earthquake hypocenters and focal mechanisms in both space and time. For this project and in close collaboration with other members of the SCEC Community Model Development Team, detailed analysis of well-determined earthquake locations and focal mechanism slip planes was used to define the geometry of active subsurface faults and to create improved, more accurate, updated digital 3D fault surface models for the SCEC Community Fault Model (CFM). Newly revised 3D models for several major fault zones, including sections of the San Andreas from Parkfield to the Salton Sea, San Jacinto, Elsinore-Laguna Salada, Agua Tibia-Earthquake Valley, Garlock, Imperial-Brawley, Landers-Joshua Tree, San Gabriel, Oak Ridge-Northridge and the San Fernando/Sierra Madre faults, as well as for several major intervening cross faults, were developed. Special attention and more detailed studies were conducted in areas of particularly complex fault geometry. This included the San Gorgonio Pass region along the San Andreas fault zone, and the Laguna Salada and adjacent Sierra Cucapah region highlighted by the 2010 M7.2 El Mayor- Cucapah sequence. These new models allow for more non-planar, multi-stranded 3D fault geometry, including changes in dip and dip direction along strike and down dip, based on the changing patterns of earthquake hypocenter and focal-mechanism nodal plane alignments, rather than projecting faults to depth assuming a constant (often vertical) dip and dip direction, as was the case for many of the previous preliminary fault models in CFM. In addition, the CFM database was reorganized with a new hierarchical name and numbering system that allows CFM to properly organize, name and number the increasing variety and complexity of modeled, multi-stranded principal slip surfaces and associated secondary faults. These new CFM fault surfaces describe a more complex pattern of interacting fault sets at depth accommodating crustal deformation in southern California, and have already provided the basis for improved dynamic rupture models, variable fault slip rate models, and correlations with associated regional topography along major active faults of the San Andreas fault system. 2

Introduction Accurate assessment of the earthquake hazards in southern California requires accurate and complete 3D fault maps. Many aspects of seismic hazard evaluation, including understanding earthquake rupture and geodetic strain, developing credible earthquake rupture scenarios, modeling geodetic and geologic fault slip rates, or predicting strong ground motion, are all strongly dependent on accurately resolving the 3D geometry of active faults at seismogenic depths [Herbert and Cooke, 2012; Lindsey et al., 2012, Oglesby and Mai, 2012; Shi et al., 2012]. In southern California, these structures can be quite complex and include both relatively high-angle strike-slip and oblique-slip faults—many of which intersect and are mapped at the surface, as well as low-to-moderate-angle faults, some of which are blind and are difficult to identify. The 1994 M6.7 Northridge earthquake was on one such blind fault and produced over $40 billion in damage. Because of this, both the Southern California Earthquake Center (SCEC) and US Geological Survey NEHRP have consistently targeted the identification and mapping in 3D of active faults in southern California as a primary research objective. The purpose of this project was to provide just such improved, more detailed, updated digital 3D fault representations of major faults in southern California for input into the online SCEC Community Fault Model (CFM) and USGS Quaternary Fault Database (Qfault). Recently, a considerable effort has been focused on developing improved catalogs of earthquake hypocenters and focal mechanism solutions for southern California (e.g., Fig.1) [e.g., Lin et al., 2007; Hauksson et al., 2012; Yang et al., 2012]. These catalogs comprise over 500,000 relocated hypocenters and nearly 200,000 well-determined earthquake focal mechanisms since 1981. These extensive catalogs need to be carefully examined and analyzed—not only for the accuracy and resolution of the earthquake hypocenters [e.g., Richards-Dinger and Ellsworth, 2001]—but also for the spatial pattern of fault slip and the orientation of 3D fault surfaces. As demonstrated by the 2010 M7.2 El Mayor-Cucapah earthquake and other events, rupture along major through-going faults in southern California can be quite complex and strongly affected by both local fault geometry and the interaction with adjacent secondary structures, such as sub-parallel fault strands, left-lateral cross faults, and basal detachments [e.g., Nicholson et al., 1986; Hudnut et al., 1989; Seeber and Armbruster, 1995; Nicholson, 1996; Carena et al., 2004; Lin et al., 2007; Nicholson et al., 2009, 2011, 2012; Hudnut et al., 2010; Fletcher et al., 2010]. Identification of these important fault features prior to a major earthquake, especially at seismogenic depths, often depends on careful analysis of microearthquake hypocenters and focal mechanisms in both space and time. To help address these issues, this project was part of an on-going, multi-year collaborative effort within SCEC to systematically upgrade and improve the Community Fault Model (CFM). Since 2010 and working in close cooperation with Andreas Plesch, John Shaw, and Egill Hauksson, we have continued to make steady and significant improvements to the CFM and its associated fault database [Nicholson et al., 2010, 2011, 2012; Plesch et al., 2010]. These improvements include more detailed and complex 3D representations of major active fault systems (Fig.1), additional detailed fault surface trace data, and finalization of our new naming and numbering scheme for CFM that allows for closer links to the USGS Qfault database. A systematic revision of CFM fault models was triggered by unexpected discrepancies between previous CFM-v.3 fault representations and the newer Qfault surface traces, as well as by the availability of the extensive relocated earthquake catalogs to better define the complex subsurface geometry of active faults. Although a draft version of CFM-v.4 was sent out for review and comment, this upgrade to CFM-v.4 is not yet complete. Many fault models in CFM-v.3 still need to be re-registered to the more detailed Qfault surface traces and, together with recent relocated hypocenters, require newer, more complex and more realistic 3D fault models for CFM. Such on-going efforts to update the 3D fault set for CFM are critical to the USGS NEHRP research priorities. This is because better knowledge of active 3D 3 fault geometry and improved 3D fault representations are fundamental to a better understanding of both fault kinematics and earthquake rupture dynamics, and are essential to improved computations of accurate strong ground motion predictions and seismic hazard assessments.

New CFM 3D faults are now registered to the Qfault surface traces and major strike-slip faults are no longer assumed to be vertical, but change dip and dip direction along strike and with depth to better correlate with the relocated hypocenters.

Thus, the purpose of this project was primarily to continue our on-going evaluation of active 3D fault geometry and development of new, updated digital 3D fault representations for CFM. In areas of unusually complex fault geometry, like San Gorgonio Pass or the El Mayor-Cucapah rupture, this project also allowed for more detailed studies of the active subsurface faults to be conducted. As a result, substantial progress was made on implementing newly revised 3D models for several major fault zones, including sections of the San Andreas from Parkfield to the Salton Sea, San Jacinto, Elsinore-Laguna Salada, Agua Tibia-Earthquake Valley, Garlock, Imperial-Brawley, Landers- Joshua Tree, San Gabriel, Oak Ridge-Northridge and the San Fernando/Sierra Madre faults, as well as for several major intervening cross faults (Fig.1) [Nicholson et al., 2012]. These new models allow for more non-planar, multi-stranded 3D fault geometry, including changes in dip and dip direction along strike and down dip, based on the changing patterns of earthquake hypocenter and focal-mechanism nodal plane alignments, rather than projecting faults to depth assuming a constant (often vertical) dip and dip direction, as is the case for many of the previous preliminary fault models in CFM-v.3. Where these faults intersect the surface, the new 3D fault models are also now properly registered to both USGS DEM and Qfault surface traces [Bryant, 2005; USGS, 2006]. In addition to updating 3D fault models for CFM, we, together with Tom Rockwell, Jerry Treiman and others have finalized a new CFM fault database hierarchical naming and numbering scheme. This allows CFM to properly organize, name and number the increasing variety and complexity of modeled, multi-stranded principal slip surfaces and associated secondary faults, while maintaining more consistency with fault nomenclature from the CGS Fault Activity database. 4 Data and Methods The primary data sets used in this and related SCEC projects are the most recent, revised catalogs of relocated earthquake hypocenters and earthquake focal mechanism solutions [Hauksson et al., 2012; Yang et al., 2012], plus USGS Digital Elevation Models of surface topography, and mapped Quaternary fault surface traces (Qfault)[Bryant, 2005; USGS, 2006]. All of these data sets are readily available online. The revised earthquake hypocenters were calculated using a procedure that involved initial relocations with absolute travel-times, source-specific station terms and a 3D velocity model, waveform cross-correlation to improve clustering and identify related earthquake pairs, and differential travel times from cross-correlated pairs to determine relative relocation within clusters [Hauksson and Shearer, 2005; Shearer et al., 2005; Lin et al., 2007; Hauksson et al., 2012]. Focal mechanisms were then determined from these revised earthquake hypocenters using both P- wave first-motions and S/P amplitude ratios [Hardebeck and Shearer, 2003; Yang et al., 2012]. For faults associated with the recent 2010 El Mayor-Cucapah sequence, the Laguna Salada fault zone, or found in the Sierra Cucapah and Yuha Desert area, we had supplemental fault surface trace maps and InSAR fault models courtesy of John Fletcher, Ken Hudnut, Jerry Treiman, and Mike Oskin [e.g., Fletcher et al., 2010; Treiman et al., 2010; Teran et al., 2011; Oskin et al., 2012]. In addition, sets of surface geologic maps, interpreted geologic cross sections and subsurface structure contour maps of stratigraphic reference horizons were used where available to help define near-surface and subsurface fault geometry in the shallow section of the fault that often exhibits little or no seismicity. These maps and cross sections are based on integrated correlations of surface geologic mapping, industry well logs and seismic reflection data [c.f., Yeats et al, 1977; Yeats, 1987, 2001; Wright, 1991; Hopps et al., 1992; Huftile and Yeats, 1995; Tsutsumi and Yeats, 1999] and can often provide geologic control of subsurface fault geometry to depths of 3 to 4 km. Similar geological and geophysical data sets, as well as maps and cross sections are also available for offshore structures [c.f., Kamerling et al., 1998, 2003; Sorlien and Kamerling, 2000; Sorlien et al., 1998, 2000, 2006, 2013; Redin et al., 2005; Nicholson et al., 2007, 2011; Hubbard, 2011; Marshall et al., 2012], and were used to generate digital 3D fault models for inclusion in CFM (Fig.1) [Kamerling et al., 2001; Schindler et al., 2007; Bennett et al., 2012]. Many of these once proprietary industry well files and seismic reflection data sets are now publicly available on-line or by request from DOGGR (c.f., http://owr.conservation.ca.gov/WellSearch/WellSearch.aspx for well files), USGS (http://walrus.wr.usgs.gov/NAMSS/ for marine seismic reflection data) and BOEMRE. The basic procedure we use is actually quite simple. We start with the earthquake hypocenters and look for alignments in map, cross section or in 3D that define discrete principal slip surfaces (Fig.2, top). These surfaces can be planar or non-planar. We then overlay the earthquake focal mechanisms (Fig.2, bottom), but generally plot only one of the two possible nodal planes and the associated slip vector (inset) [Seeber and Armbruster, 1995]. If the alignment of the dominant focal mechanism nodal planes is consistent with the alignment of hypocenters, then the principal slip surface is considered well resolved. Generally, the best orientation for identifying such principal slip surfaces is to look in 3D down-dip or along strike in the plane of slip for the fault. Digital 3D fault surfaces were then generated in several ways, depending on the available data, and the quality and distribution of the hypocenters and nodal planes. If the hypocenters could define a discrete slip surface with non-planar fault geometry, a best-fitting gridded surface with varying smoothing constraints was constructed with these events. If the events only defined a general linear trend, then a best-fitting median plane was constructed through the earthquake distribution. Faults with a mapped surface traces were generally constructed by projecting a smoothed version of the surface trace to depth, but with changing dip and fault geometry along strike, that best matched the changing geometry of discrete hypocenter clusters or dip of the predominant nodal plane (Figs.3-5). 5

Mission San Andreas fault system Creek, Banning and Garnet Hill faults typically dip 70° to 80°NE, and each is a distinctly separate PSF fault to 8-10 km. Different interpretations are permissible, e.g., the orange North Palm Springs fault could be the active down-dip extension of the gray

Enlarged oblique 3D view of Fig.3 looking down-dip of the Palm Springs fault (PSF), but now showing some of the new updated 3D fault surfaces created for CFM-v4 that represent the set of deep en echelon NE-dipping blind faults defined by PSF San Andreas fault zone linear trends in hypocenter and nodel plane alignments. Several of these fault models, including the Palm Springs fault, are nearly identical to previous independently derived 3D fault models based on earlier relocated catalogs and different surface-fitting San Jacinto fault zone algorithms [Carena et al., 2004]. 7

This kinematic technique of using the spatial distribution of earthquake hypocenters and focal mechanisms to define the geometry of active subsurface faults has proven to be very effective in southern California [Nicholson et al., 1986; Nicholson and Seeber, 1989; Seeber and Armbruster, 1995; Carena et al., 2004]. The power of this technique lies in the internal consistency between two relatively independent datasets: (1) the spatial distribution of the earthquake hypocenters in 3D defined by earthquake travel-times, and (2) the kinematic compatibility and alignment in 3D of individual nodal planes defined by earthquake first-motions and amplitude ratios. A simple example of this technique is demonstrated by a set of steeply dipping, blind, oblique to predominantly strike-slip en echelon faults that occur at depths below about 10 km beneath San Gorgonio Pass. Figure 3 shows a map view looking NE of this deep seismicity, together with some of the new revised 3D fault models we developed for CFM-v4. This includes the Mill Creek, Mission Creek, Banning, and Garnet Hill fault strands, as well as other secondary faults such as the San Gorgonio Pass thrust, the North Palm Springs fault, and the new blind Palm Springs fault (green, PSF). The Palm Springs fault represents one of these deep blind, oblique en echelon faults. The reason we believe we can confidently identify and map these structures as distinctly separate faults is because of the consistency produced by the hypocenter and nodal plane alignments when looking down-dip or along strike in the plane of slip of each fault. Thus, if we rotate the entire frame of reference of this earthquake and fault volume until we are looking down-dip and in the plane of slip of the Palm Springs fault (Fig.4), the earthquakes along the Palm Springs fault (PSF) now define a very narrow linear trend, as they should if most of the events represent slip along this single principal slip surface. This geometry is also consistent with the geometry of the predominant NW-striking, NE-dipping nodal plane many of these earthquakes exhibit in their focal mechanism solutions [e.g., Carena et al., 2004]. Moreover, this frame of reference, highlights other faults in this set of deep, en echelon strike-slip to oblique slip faults that have remarkably similar NE dips. These faults are in addition and sub-parallel to the principal slip surfaces of the San Andreas fault zone, and thus help accommodate plate boundary strain through San Gorgonio Pass. This fault set was first identified by Seeber and Armbruster [1995] and confirmed by Carena et al. [2004], and the resulting 3D fault models developed for CFM-v4 (Fig.5) are virtually identical to previous non- planar 3D fault surfaces independently created using an earlier catalog of relocated focal mechanism solutions and different surface-fitting algorithms [Carena et al., 2004]. Results For this project and in collaboration with other members of the Community Model Development Team, substantial progress was made on implementing newly revised 3D models for several major fault zones, including sections of the San Andreas from Parkfield to Cajon Pass, Garlock, Imperial- Brawley, Laguna Salada-Sierra Cucapah, Lenwood-Lockhart, Landers-Joshua Tree, San Gabriel, Oak Ridge-Northridge and the San Fernando/Sierra Madre faults, as well as for several major cross faults (Fig.1)[Nicholson et al., 2012]. These new models expand the lexicon of revised 3D fault models previously developed for CFM-v.4 that include the San Andreas fault from San Gorgonio Pass to the Salton Sea, the adjacent sub-parallel Mecca Hills-Hidden Springs fault zone, and the San Jacinto, Elsinore-Laguna Salada, and Agua Tibia-Earthquake Valley fault systems [Nicholson et al., 2011]. Several of these earlier CFM-v4 fault models were subsequently revised and updated as part of this project based on additional information and after community review and comment. In addition, this project was able to support more detailed studies in areas of particularly complex fault geometry where multiple fault sets and sub-parallel fault zones strongly interact. This included the complex San Gorgonio Pass region along the San Andreas fault, and the Laguna Salada-Indiviso- Sierra Cucapah region at the southern end of the Elsinore-Laguna Salada fault zone and associated with the El Mayor-Cucapah sequence. This report will focus on many of these special fault areas. 8 Southern San Andreas and Mecca Hills-Hidden Springs fault zones In constructing 3D fault models for CFM, special care was taken to distinguish between sub- parallel fault strands or secondary fault systems. For example, Figure 6 shows a slightly oblique map view of some of our new CFM-v4 3D fault representations along the southern San Andreas fault (SSAF) extending from San Gorgonio Pass through the Coachella Valley to the Salton Sea [Nicholson et al., 2011, 2012]. This includes active strands and down-dip splays of the Banning, Garnet Hill, Mission Creek, North Palm Springs, San Gorgonio Pass thrust, and Southern San Andreas faults, as well as a 3D model for the adjacent, sub-parallel Mecca Hills-Hidden Springs fault. The Mecca Hills-Hidden Springs fault is an active NE-dipping sub-parallel structure adjacent to the SSAF that is responsible for the bulk of the seismicity located east of the southern San Andreas surface trace. Previous investigators have inferred that this seismicity may be produced by a dipping SSAF that dips NE at about 65°-67° [e.g., Fuis et al., 2007] based mainly on the projection of seismicity and nodal plane alignments near Salt Creek [Lin et al., 2007]. However, further study of this seismicity, clearly shows that this dipping principal slip surface strikes oblique to the SSAF surface trace and progressively projects to crop out several kilometers farther east as one moves north [Nicholson et al., 2010]. In all cases along strike of this structure, including at Salt Creek, the earthquake and nodal plane alignments project to intersect the down-dip extension of mapped intervening surface faults, like the Hidden Springs, Mecca Hills and Painted Canyon faults.

Figure 6. Slightly oblique 3D view looking NE and nearly down-dip of the Mecca Hills-Hidden Springs fault adjacent to the Southern San Andreas fault (SSAF). This secondary fault system strikes oblique to the SSAF and is responsible for the dipping seismicity found east of the SSAF surface trace, the mapped surface faults east of the SSAF surface trace (like Indio Hills, Painted Canyon, Mecca Hills and Hidden Springs), and regional topography not explained by SSAF slip.

The presence of both a dipping Mecca Hills-Hidden Springs fault system and a vertical or near- vertical SSAF has significant implications. First, it can help explain observations that are otherwise difficult to reconcile. For example, a few scattered earthquakes do occur directly beneath the SSAF surface trace, seismic reflection data along the SSAF suggest a steep to near vertical fault [Rymer et al, 2012; Catchings et al., 2012; Goldman et al., 2012], and the SSAF is clearly vertical at Bombay 9 Beach where it intersects the Brawley Seismic Zone based on earthquake and nodal plane alignments [Nicholson et al., 2010]. However, geodetic data along the SSAF indicate that maximum shear strain is displaced about 7 km NE of the SSAF surface trace [Fialko, 2006]. This could be the result of the active NE-dipping Mecca Hills-Hidden Springs fault working in combination with a vertical SSAF, rather than shear strain only accumulating on what would otherwise be an inferred dipping SSAF. The presence of two active fault systems side-by-side implies, however, that some plate motion is already being diverted from the SSAF onto the Eastern California shear zone as far south as Bombay Beach, and not necessarily only at the Indio Hills where the southernmost end of the Landers-Joshua Tree sequences begin to splay off from the main SSAF system. San Gorgonio Pass Along the San Andreas fault proper, there is no place more complex, more enigmatic, or more important to properly understand in 3D than San Gorgonio Pass (SGP)[Yule, 2009] and its extension to Cajon Pass where the major San Andreas and San Jacinto fault zones intersect (Figs.1-3,7). Knowing the subsurface geometry of active faults in this area is critical for properly extrapolating near-surface observations to depth, and is particularly important in such complex areas where principal slip surfaces can be multi-stranded, exhibit significant non-planar subsurface fault geometry, and/or intersect other adjacent major faults. The geometry and nature of active fault strands is also crucial to resolving the potential for large through-going rupture, and the resulting strong ground motion predictions for different SSAF rupture scenarios. San Gorgonio Pass and its surrounding region are currently designated a SCEC Special Fault Study Area [Yule et al., 2012]. Accurate representations of 3D fault surfaces through the Pass are thus not only fundamental to the basic seismic hazard estimation for southern California, but provide the necessary framework for all such future integrated tectonic, geologic, and geophysical studies of this particular fault area. 10

Figure 7. Map of relocated earthquake hypocenters color-coded by depth [Hauksson et al., 2012]. To first-order, the geometry of the major through-going fault is defined by the San Andreas- Banning surface trace (red line) and the down-dip NE extent of the deeper earthquakes (solid orange line). Dashed red line is the actual linear trend of deeper seismicity that defines a steeply dipping, through-going predominantly strike-slip San Andreas fault strand, while the cluster of green to yellow events farther east represent oblique thrust faults in its hangingwall.

A major question has always been: what is the geometry of the principal active strand of the San Andreas fault (SAF) through San Gorgonio Pass? Figure 7 shows a map of the most recent relocated hypocenters [Hauksson et al., 2012] with the earthquakes color-coded by depth. This figure actually shows the geometry of this fault quite well. It is basically defined by the SAF surface trace (red line) and the down-dip NE extent of the deeper earthquakes shown by the dark blue and magenta colors (orange line). In actuality, the alignment in 3D of the earthquake hypocenters and nodal planes tends to suggest something a bit more linear (dashed red line), but the general shape is still one of a steep NE-dipping through-going fault with a dip in the northern Coachella Valley of about 70°. The light blue, green and yellow events at shallower levels farther east are mostly aftershocks of the 1986 North Palms Springs earthquake. They help define moderately dipping secondary oblique thrust faults in the hanging-wall of this more steeply dipping San Andreas fault. This interpretation of a through-going, steeply dipping SAF, and one or more moderately dipping oblique thrust faults in its hanging-wall is not new. Both Seeber and Armbruster [1995] and Carena et al. [2004] were able to identify nearly identical fault structures based on the alignment of relocated hypocenters and focal mechanism nodal planes. This fault geometry is also not surprising as it is very similar to the geometry of the San Andreas fault through the Santa Cruz Mountains, where similar oblique motion is again partitioned between a near-vertical SAF, and a more moderately dipping oblique dip-slip fault that produced the 1989 Loma Prieta earthquake [Seeber and Armbruster, 1990]. The new, more extensive relocated earthquake catalogs we use for CFM-v4 basically reaffirm this earlier interpretation. The only difference is that in CFM-v4, we distinguish between the shallow San Gorgonio Pass thrust fault that is largely defined by surface geologic mapping, and the deeper North Palm Springs fault defined by seismicity to emphasize that these two sections are defined by different data sets, and that this structure, if continuous, appears to be offset both vertically and horizontally by the through-going Banning fault strand of the SAF. In previous interpretations, the North Palm Springs fault would be simply labeled as the down-dip extension of the San Gorgonio Pass thrust. This is a very viable, reasonable interpretation and both alternative representations, as well as those from Carena et al. [2004] are included in CFM-v4. Figure 8 shows a map view of the many new 3D fault models through San Gorgonio Pass we developed for CFM [Nicholson et al., 2012]. In developing these new 3D fault representations, care was taken that fault models were first smoothed to reduce artifacts of model construction, and if the fault extended to surface outcrop, the fault was registered to both DEM and the Qfault surface trace. In this way, 3D models for active strands and down-dip splays of Banning, Garnet Hill, Mission Creek, Mill Creek, San Gorgonio Pass thrust, North Palm Springs, and southern San Andreas faults (SSAF) were created. Subsequently, faults in the Crafton Hills complex and representations for the set of blind en echelon faults (Fig.5), like Palm Springs and other secondary faults beneath San Gorgonio Pass were also added. The advantage of these new models is that they allow for more variability in dip along strike and with depth, are more consistent with alignments of relocated hypocenters and focal mechanism nodal planes, and have a higher concentration of hypocenters within close proximity (±1 km) of the modeled 3D slip surface [Hauksson, 2012] than previous CFM fault models. The new 3D fault models also help characterize a more complex pattern of fault 11 interactions at depth between various fault sets and linked fault systems, while providing more continuous, multiple, through-going fault surfaces through San Gorgonio Pass.

Figure 8. New CFM-v.4 fault models for the San Andreas fault system through San Gorgonio Pass [Nicholson et al., 2012]. Three distinctly separate fault strands (Mission Creek, Banning, and Garnet Hill) are now defined in the northern Coachella Valley, and are typically steeply dipping and sub-parallel to depths of 8–10 km. The presence of the principal through-going Banning strand at depth increases the possibility of dynamic rupture through the pass [Shi et al., 2012], while the Crafton Hills complex affects SAF slip rates [Herbert, 2012].

The degree of fault complexity in San Gorgonio Pass is exemplified by the fact that at least 4 different sets of interacting fault structures have been identified, and each set needs to be mapped in detail if the pattern of stress and strain is to be properly modeled and understood. These fault sets include: 1) the principal NW-striking slip surfaces inferred to accommodate the bulk of strike-slip motion along the fault zone (Fig.8). These are typically steeply (~70°–80°) NE-dipping faults, such as the Banning, Garnet Hill and Mission Creek strands, and can extend throughout the seismogenic crust; 2) sets of NE-striking, high-angle secondary cross faults found primarily in the upper 10 km, such as the Crafton Hills fault complex; 3) predominantly NE-dipping moderate-to-low-angle (~30°–45°) oblique thrust faults that occur at depths below ~8-10 km. These would include faults involved in the 1986 North Palm Springs sequence, like the North Palm Springs fault, as well as other mid-crustal and basal detachments; and 4) the series of previously mentioned en echelon NW- striking oblique strike-slip faults that typically dip ~65°NE, such as the blind Palm Springs fault (PSF)(Fig.5), and which also occur primarily below ~10 km [Nicholson et al., 1986; Nicholson and Lees, 1992; Seeber and Armbruster, 1995; Nicholson, 1996; Carena et al., 2004; Nicholson et al., 2010]. As with the PSF, many of these secondary fault sets are best expressed by looking down-dip or along strike within the plane of slip (e.g., Fig.4), and Figure 9 shows a vertical cross section looking nearly along strike of the Banning and Garnet Hill fault strands (Fig.4, red box + arrow). In cross section, the first-order feature we see in the seismicity is a fairly distinct separation of seismic activity in the upper and lower crust. The upper crust exhibits less seismicity that defines a 12 few steeply dipping strike-slip to oblique-slip faults, while in the lower crust, the higher level of earthquake activity tends to define a wedge-shaped volume that contains more low-angle reverse or oblique-reverse faults. The boundary between these two crustal layers appears to be at about 10 to 12 km depth (dashed white line, Fig.9). In places, this very low-angle dipping interface appears to be seismically active, as it exhibits alignments of hypocenters and low-angle nodal planes (inset, Nicholson and Lees, 1992). It may also have been responsible for truncating the down-dip extent of the North Palm Springs rupture in 1986 [Nicholson, 1996]. As such, this interface or detachment may reflect a significant mechanical layering to the seismogenic crust, and may help explain why the shallow mapped geologic structures and other near-surface observations in San Gorgonio Pass may not necessarily correlate well with the deeper active faults.

Figure 9. Cross section looking NW along strike of Banning fault (see Fig.4 for orientation) showing how the steeply dipping Garnet Hill (GHF, yellow), Banning (BF, purple) & Mission Creek (MCF) fault strands intersect and merge with a set of low-angle oblique thrust faults. Seismicity appears to exhibit mechanical layering (dashed line) that may be active (inset) and controlled the down-dip extent of rupture in 1986 [Nicholson and Lees, 1992]. Through-going BF & GHF may remain steeply dipping and relatively planar (Option #1), become more listric (Option #2), or do both to splay down- dip and become multi-stranded at depth. Alternatively, these can just be considered separate fault sets.

This mechanical layering may also affect to some extent the geometry and behavior of major through-going faults. Earthquakes currently occur along the through-going Banning fault strand, but primarily at depths below this mid-crustal detachment (Fig.2). In the upper crust, the Garnet Hill, Banning and Mission Creek fault strands remain steeply dipping and sub-parallel down to about 8- 10 km, or about the depth of this detachment (Fig.9). At deeper levels, however, they begin to interact and merge with a set of moderately-dipping oblique thrust faults. Thus, faults like the 13 Garnet Hill strand can remain steeply-dipping (Option #1), it can become more listric (Option #2), or do both and splay down-dip to become multi-stranded at depth. This is also true for the Banning which can remain steeply-dipping (Option #1), it can become more listric (Option #2), or merge with the faults active during the 1986 North Palm Springs sequence (Option #3). The main point is that both fault sets: steeply dipping through-going predominantly strike-slip faults (like the Banning and Garnet Hill strands), and more moderately dipping oblique thrust faults (like the North Palm Springs fault), are present, active and interacting with each other. This allows the fault system to accommodate both through-going predominantly strike-slip motion along the more steeply dipping planar fault strands, like the Banning, but also a secondary component of crustal shortening and reverse slip on the more moderately dipping oblique thrust faults present in the hangingwall. The new 3D fault models developed for CFM-v4 thus help characterize a more complex pattern of fault interactions at depth between various fault sets, while providing more continuous, steeply dipping and smoothly varying rupture surfaces through San Gorgonio Pass. These more complete, detailed, and more complex multiple 3D fault models may help explain some of the more enigmatic fault behavior and patterns of deformation that may be otherwise difficult to understand. For example, the failure of the 1986 North Palm Springs mainshock to develop into a full-scale rupture of the SSAF could be the result of it occurring primarily on the adjacent secondary North Palm Springs fault (Fig.9), rather than on what might be considered the primary, more steeply dipping through-going Banning fault strand (Option #1, Fig.9). Moreover, the decrease in slip rate observed SE along strike of the San Bernardino strand of San Andreas fault in San Gorgonio Pass may be related to adjacent secondary faults, like the Crafton Hills complex [Herbert and Cooke, 2012] and to slip being more distributed as the fault becomes multi-stranded at depth (Fig.8), rather than changing geometry of a single fault as was once believed [Dair and Cooke, 2009]. Laguna Salada and Sierra Cucapah faults, and the 2010 El Mayor-Cucapah sequence Besides developing updated 3D fault models along major mapped surface traces (e.g., Fig.1), substantial effort was also made to develop preliminary 3D fault models for several major recent earthquake ruptures. This included fault models for the 1971 San Fernando, 1979 Imperial Valley, 1986 North Palm Springs, 1987 Elmore Ranch-Superstition Hills, 1992 Landers-Joshua Tree, 1994 Northridge, and 2010 El Mayor-Cucapah earthquakes and their associated aftershocks. The 2010 El Mayor-Cucapah earthquake was particularly complex [Hudnut et al., 2010; Kroll et al., 2012], and demonstrated that major earthquakes can occur on adjacent sub-parallel faults in close proximity to previous large earthquakes on distinctly separate structures (e.g., 1892 M7 Laguna Salada earthquake). Figure 10 shows an oblique 3D view of some of the new fault models we developed for this 2010 sequence, as well as for various cross faults and active strands of the Laguna Salada fault, based on an integrated analysis of the relocated aftershocks [Hauksson et al., 2011; 2012], and near-surface geologic mapping and InSAR studies of fault surface traces [e.g., Fletcher et al., 2010; Oskin et al., 2011, 2012; Teran et al., 2011; Treiman et al., 2010]. Several of these CFM models were subsequently revised following comment and review of preliminary ones presented at the 2011 SCEC meeting. The new CFM 3D models include fault representations for the Borrego, Pescadores, Paso Superior, Paso Inferior, Sierra Cucapah, and Indiviso faults, as well as adjacent dipping strands of the Laguna Salada fault and various associated cross faults like Painted Gorge Wash, Devil's Canyon, Yuha Well, Shell Beds, Yuha Wash, Yuha, and El Mayor-Cucapah cross faults. In constructing these new 3D models, we distinguished between the predominantly steep to E- dipping shallow faults and related fault splays that we correlate to the major, deep E-dipping Sierra Cucapah fault, and the predominantly steep to W-dipping strands and down-dip splays related to the Laguna Salada fault. Numerous cross faults and other secondary faults were triggered by the 2010 event. Many of these correlated well with mapped surface fault traces, while others remained blind. 14

Reorganization of the CFM fault database In collaboration with the Community Model Development Team and the SCEC Earthquake Geology Group, the CFM-v4 fault database was reorganized with a new hierarchical name and numbering scheme. This reorganization allows CFM to properly organize, name and number the increasing variety and complexity of modeled, multi-stranded principal slip surfaces, adjacent secondary faults, and alternative fault representations that have been or will be developed for CFM, while maintaining a greater consistency with fault nomenclature from the CGS Fault Activity database. The new CFM database naming scheme provides unique identifiers (including number, name and abbreviation) for each level of the fault hierarchy under which a particular fault segment is classified. Levels of hierarchy include Fault Area, Fault Zone or System, Fault Section, Fault Name, Fault Strand or Model, and Fault Component (Fig.11). These additional hierarchical levels allow for more flexible database searches and easier identification of fault components and possible system-level associations of individual 3D fault elements that comprise CFM. This scheme also allows for grouping related individual faults under a higher-level fault system (e.g., Southern Frontal Fault System for the Raymond, Hollywood, Santa Monica, and Malibu Coast faults) to help facilitate identification of potentially larger earthquake ruptures between such kinematically linked and geometrically similar multiple fault segments. In 2012, a draft version this new fault database was sent out for review, comment and ranking of alternative fault models in CFM. Appendix 1 provides a partial listing of the database with current revised CFM fault names, numbers and abbreviations. However, this spreadsheet is still a work in progress, as it needs to more fully incorporate feedback, review comments, and fault rankings provided to us by the USGS, CGS and other SCEC colleagues. 01 10 13 11 09 08 SCEC CFM-v4 Fault Database - Fault Area/Major Boundary 08 01 - San Andreas fault system 02 - Salton Trough fault area 12 03 - Peninsular Ranges fault area 07 04 - Offshore Continental Borderland 01 05 - Western Transverse Ranges area 05 06 - Eastern Transverse Ranges area 01 07 - Mojave fault area 08 - Garlock fault system 06 09 - Basin and Range fault area Figure 11.

Conclusions For this project, alignments of relocated earthquake hypocenters and focal mechanism nodal planes were thus used to define the subsurface 3D geometry of active faults and to construct updated digital 3D fault representations for CFM (Fig.1). These new models allow for more non- planar, multi-stranded 3D fault geometry, including changes in dip and dip direction along strike and down dip, based on the changing patterns of earthquake hypocenter and focal-mechanism nodal plane alignments, rather than projecting faults to depth assuming a constant (often vertical) dip and dip direction, as was the case for many of the previous preliminary fault models in CFM. These fault surfaces are often best resolved when looking in 3D down-dip or along strike within the plane of slip for each fault (Figs.2,4,6&9). Along major through-going faults in southern California, recent earthquake fault ruptures, such as the 2010 El Mayor-Cucapah earthquake that involved the deep Sierra Cucapah fault and associated fault splays (Fig.10), appear to be strongly affected by local fault geometry, as well as the sense of slip and relative orientation of secondary structures, such as left-lateral conjugate cross faults, tear faults, and low-angle detachments. Identification of these features, especially at seismogenic depths, often depends on careful kinematic analysis of the earthquake hypocenters and focal mechanisms in both space and time. In the Coachella Valley and at its intersection with the Brawley Seismic zone below the Salton Sea, alignments of hypocenters and nodal planes, together with seismic reflection data strongly suggest the Southern San Andreas fault (SSAF) is vertical to steeply dipping, while earthquakes located farther east define a separate Mecca Hills-Hidden Springs fault zone (Fig.6) that dips NE at about 65° to 70°. This principal slip surface strikes oblique to the SSAF and so would project to crop out several kilometers east of the SSAF surface trace at the latitude of the Indio Hills. This dipping fault zone, sub-parallel and adjacent to the SSAF, is responsible for the mapped secondary faults and elevated, tectonically deformed topography found in this area that can not be explained by strike-slip motion on a vertical or near-vertical SSAF. The presence of both fault zones side-by- side implies that some plate boundary motion is likely diverted onto the Eastern California shear zone as far south as Bombay Beach. Through San Gorgonio Pass (SGP), seismicity appears to define a mechanically layered crust with predominantly high-angle strike-slip to oblique slip faults in the upper crust, while beneath ~10 km depth, intersecting sets of strike-slip, oblique slip and low-angle thrust faults define a more complex wedge-shaped volume deformation of the lower crust (Figs.2-5,8&9). In some places, this interface between upper and lower crustal deformation appears to be seismically active and may have controlled the down-dip extent of seismic rupture in 1986. Alignments of hypocenters and nodal planes define multiple principal slip surfaces through SGP (Figs.8-9), including a through- going steeply-dipping (~70°) predominantly strike-slip Banning strand at depth and a more moderately-dipping (40°-50°) oblique North Palm Springs fault that both project upwards towards the San Andreas fault (SAF) surface trace. The North Palm Springs fault may be the active down- dip extension of the San Gorgonio Pass thrust offset at depth by the principal, through-going steeply dipping Banning strand of the SAF. In the northern Coachella Valley, seismicity indicates that the Garnet Hill and Banning strands of the SAF are most likely sub-parallel and steeply dipping (~70°NE) to depths of 8–10 km, where they intersect and merge with a stack of moderately dipping to low-angle oblique thrust faults (Fig.9). Although the dense wedge of deep seismicity below SGP contains multiple secondary fault sets of different orientations, the predominant fault set appears to be a series of en echelon NW- striking strike-slip to oblique-slip faults that dip NE and strike slightly oblique to the SAF (Figs.4- 5). These faults also help accommodated plate boundary motion through SGP. 17 These revised 3D models for the principal slip surfaces through San Gorgonio Pass and into the Coachella Valley, including the Mecca Hills-Hidden Springs fault, have already proven useful to modeling dynamic earthquake rupture along the San Andreas fault [Shi et al., 2012; Tarnowski and Oglesby, 2012], as well as providing a better match to the observed patterns of geodetic strain [Fialko, 2006], tectonic uplift and regional topography in the Coachella Valley and adjacent Little San Bernardino Mountains [Fattaruso and Cooke, 2012]. Furthermore, the presence of additional active secondary faults, such as the Crafton Hills complex and blind faults at depth below San Gorgonio Pass, like the Palm Springs fault (Fig.8), are also important as they can strongly influence modeled slip rates along the San Andreas fault itself [e.g., Herbert and Cooke, 2012]. The new 3D fault models developed for CFM-v4 help characterize a more complex pattern of fault interactions at depth between various fault sets, sub-parallel fault systems, and intersecting secondary cross faults and low-angle detachments. To properly organize, name and number the increasing variety and complexity of these modeled, multi-stranded principal slip surfaces, adjacent secondary faults, and alternative fault representations, the SCEC CFM database was reorganized with a new hierarchical name and numbering scheme (Fig.11 & Appendix 1). This new fault ID scheme allows for more flexible database searches, and easier identification of possible system- level associations of individual 3D fault elements that comprise CFM to help facilitate identification of potentially larger earthquake ruptures between various kinematically linked and geometrically similar faults and multiple fault segments. Data and Product Availability The primary earthquake datasets used for this research are available from the SCEC Data Center (http://data.scec.org/research-tools/altcatalogs.html). Most mapped fault surface trace data we used were provided by the California Geological Survey primarily through the USGS Quaternary Fault and Fold database website (http://earthquake.usgs.gov/hazards/qfaults/).

Non-technical Summary Detailed analysis of well-determined earthquake locations and focal mechanisms are used to define the geometry of active subsurface faults and to create improved, updated digital 3D fault surface models for the SCEC Community Fault Model (CFM). Newly revised 3D models for several major fault zones, including the San Andreas from Parkfield to the Salton Sea, San Jacinto, Elsinore-Laguna Salada, Agua Tibia-Earthquake Valley, Garlock, Imperial-Brawley, Mecca Hills- Hidden Springs, Pinto Mountain, Landers-Joshua Tree, San Gabriel, Oak Ridge-Northridge and the San Fernando/Sierra Madre faults were developed, including detailed models for the San Gorgonio Pass and El Mayor-Cucapah regions. These new models allow for more non-planar, multi-stranded 3D fault geometry, including changes in dip and dip direction along strike and down dip, based on the changing patterns of earthquake hypocenter and focal-mechanism nodal plane alignments. These new CFM fault surfaces describe a more complex pattern of interacting fault sets at depth accommodating crustal deformation in southern California, and have already provided the basis for improved dynamic earthquake rupture models, variable fault slip rate models, and correlations with associated regional topography.
