Distribution and Sedimentary Characteristics of Tsunami Deposits
Sedimentary Geology 200 (2007) 372–386 www.elsevier.com/locate/sedgeo Distribution and sedimentary characteristics of tsunami deposits along the Cascadia margin of western North America ⁎ Robert Peters a, , Bruce Jaffe a, Guy Gelfenbaum b a USGS Pacific Science Center, 400 Natural Bridges Drive, Santa Cruz, CA 95060, United States b USGS 345 Middlefield Road, Menlo Park, CA 94025, United States Abstract Tsunami deposits have been found at more than 60 sites along the Cascadia margin of Western North America, and here we review and synthesize their distribution and sedimentary characteristics based on the published record. Cascadia tsunami deposits are best preserved, and most easily identified, in low-energy coastal environments such as tidal marshes, back-barrier marshes and coastal lakes where they occur as anomalous layers of sand within peat and mud. They extend up to a kilometer inland in open coastal settings and several kilometers up river valleys. They are distinguished from other sediments by a combination of sedimentary character and stratigraphic context. Recurrence intervals range from 300–1000 years with an average of 500–600 years. The tsunami deposits have been used to help evaluate and mitigate tsunami hazards in Cascadia. They show that the Cascadia subduction zone is prone to great earthquakes that generate large tsunamis. The inclusion of tsunami deposits on inundation maps, used in conjunction with results from inundation models, allows a more accurate assessment of areas subject to tsunami inundation. The application of sediment transport models can help estimate tsunami flow velocity and wave height, parameters which are necessary to help establish evacuation routes and plan development in tsunami prone areas. -

Oceanography of the Pacific Northwest Coastal Ocean and Estuaries with Application to Coastal Ecosystems
Oceanography of the Pacific Northwest Coastal Ocean and Estuaries with Application to Coastal Ecosystems Barbara M. Hickey1 and Neil S. Banas School of Oceanography Box 355351 University of Washington, Seattle, WA 98195-7940 Tel.: 206 543 4737 e-mail: [email protected] Submitted to Estuaries May 2002 1Corresponding author. Hickey and Banas 2 Abstract This paper reviews and synthesizes recent results on both the coastal zone of the U.S. Pacific Northwest (PNW) and several of its estuaries, as well as presenting new data from the PNCERS program on links between the inner shelf and the estuaries, and smaller-scale estuarine processes. In general ocean processes are large-scale on this coast: this is true of both seasonal variations and event-scale upwelling-downwelling fluctuations, which are highly energetic. Upwelling supplies most of the nutrients available for production, although the intensity of upwelling increases southward while primary production is higher in the north, off the Washington coast. This discrepancy is attributable to mesoscale features: variations in shelf width and shape, submarine canyons, and the Columbia River plume. These and other mesoscale features (banks, the Juan de Fuca eddy) are important as well in transport and retention of planktonic larvae and harmful algae blooms. The coastal-plain estuaries, with the exception of the Columbia River, are relatively small, with large tidal forcing and highly seasonal direct river inputs that are low-to-negligible during the growing season. As a result primary production in the estuaries is controlled principally not by river-driven stratification but by coastal upwelling and bulk exchange with the ocean. -

Paleoseismicity of the Southern End of the Cascadia Subduction Zone, Northwestern California by David W
Bulletin of the Seismological Society of America, Vol. 102, No. 3, pp. 1059–1078, June 2012, doi: 10.1785/0120110103 Ⓔ Paleoseismicity of the Southern End of the Cascadia Subduction Zone, Northwestern California by David W. Valentine, Edward A. Keller, Gary Carver, Wen-Hao Li, Christine Manhart, and Alexander R. Simms Abstract The southern end of the Cascadia subduction zone (CSZ) in northwestern California poses a high seismic hazard. This study uses the Quaternary stratigraphy of the bays and estuaries to reconstruct coseismic subsidence caused by strong to great earthquakes. We used lithology, macrofossils, and microfossils to estimate the amount of relative sea-level change at contacts caused by coseismic subsidence. Our paleo- seismic record contains evidence of four to six earthquakes over the past 2000 years. Using the pattern and magnitude of submergence and other paleoseismic information (trenches and other sites), we determine whether the earthquakes were local or regio- nal. We found that the record contained evidence for both smaller strong to major earthquakes on local structures (Mw 6.5–7.2) and larger regional subduction-zone- M >8:2 related great earthquakes ( w ). We compared our record to other records from Oregon and Washington and found three earthquakes likely caused by the rupture of the entire CSZ around approximately 230–270 (the A.D. 1700 event), 1150–1400, and 1750–1900 cal B.P. In addition, two other local earthquakes likely occurred around 500–600, 1000–1250, and possibly 1500–1650 cal B.P. Online Material: Table of radiocarbon ages obtained in the study.
