Damage Assessment of the 2015 Mw 8.3 Illapel Earthquake in the North‑Central Chile
Natural Hazards https://doi.org/10.1007/s11069-018-3541-3 ORIGINAL PAPER Damage assessment of the 2015 Mw 8.3 Illapel earthquake in the North‑Central Chile José Fernández1 · César Pastén1 · Sergio Ruiz2 · Felipe Leyton3 Received: 27 May 2018 / Accepted: 19 November 2018 © Springer Nature B.V. 2018 Abstract Destructive megathrust earthquakes, such as the 2015 Mw 8.3 Illapel event, frequently afect Chile. In this study, we assess the damage of the 2015 Illapel Earthquake in the Coquimbo Region (North-Central Chile) using the MSK-64 macroseismic intensity scale, adapted to Chilean civil structures. We complement these observations with the analysis of strong motion records and geophysical data of 29 seismic stations, including average shear wave velocities in the upper 30 m, Vs30, and horizontal-to-vertical spectral ratios. The calculated MSK intensities indicate that the damage was lower than expected for such megathrust earthquake, which can be attributable to the high Vs30 and the low predominant vibration periods of the sites. Nevertheless, few sites have shown systematic high intensi- ties during comparable earthquakes most likely due to local site efects. The intensities of the 2015 Illapel earthquake are lower than the reported for the 1997 Mw 7.1 Punitaqui intraplate intermediate-depth earthquake, despite the larger magnitude of the recent event. Keywords Subduction earthquake · H/V spectral ratio · Earthquake intensity 1 Introduction On September 16, 2015, at 22:54:31 (UTC), the Mw 8.3 Illapel earthquake occurred in the Coquimbo Region, North-Central Chile. The epicenter was located at 71.74°W, 31.64°S and 23.3 km depth and the rupture reached an extent of 200 km × 100 km, with a near trench rupture that caused a local tsunami in the Chilean coast (Heidarzadeh et al. -

The Chiloé Mw 7.6 Earthquake of 25 December 2016 in Southern Chile and Its Relation to the Mw 9.5 1960 Valdivia Earthquake
2016 Chiloé Earthquake, Southern Chile submitted to Geophysical Journal International The Chiloé Mw 7.6 earthquake of 25 December 2016 in Southern Chile and its relation to the Mw 9.5 1960 Valdivia earthquake 1 2 3 3 Dietrich Lange , Javier Ruiz , Sebastián Carrasco , Paula Manríquez (1) GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany (2) Departamento de Geofísica, Facultad de Ciencias Físicas y Matemáticas, Universidad de Chile, Santiago, Chile (3) National Seismological Centre, University of Chile, Santiago, Chile Keywords: 2016 Chiloé earthquake, Subduction Zone, Southern Chile, 1960 Valdivia Earthquake Corresponding author: Dietrich Lange (email: [email protected]) Abstract On 25 December 2016, a Mw 7.6 earthquake broke a portion of the Southern Chilean subduction zone south of Chiloé Island, located in the central part of the Mw 9.5 1960 Valdivia earthquake. This region is characterized by repeated earthquakes in 1960 and historical times with very sparse interseismic activity due to the subduction of a young (~15 Ma), and therefore hot, oceanic plate. We estimate the co-seismic slip distribution based on a kinematic finite fault source model, and through joint inversion of teleseismic body waves and strong motion data. The coseismic slip model yields a total seismic moment of 3.94×1020 Nm that occurred over ~30 s, with the rupture propagating mainly downdip, reaching a peak-slip of ~4.2 m. Regional moment tensor inversion of stronger aftershocks reveals thrust type faulting at depths of the plate interface. The fore- and aftershock seismicity is mostly related to the subduction interface with sparse seismicity in the overriding crust. -
Seismic Performance of Tailings Sand Dams in Chile
16th World Conference on Earthquake, 16WCEE 2017 Santiago Chile, January 9th to 13th 2017 Paper N° 4230 Registration Code: S-V1461865061 Seismic performance of tailings sand dams in Chile J. H. Troncoso (1), R. Verdugo (2), L. Valenzuela (3) (1) Senior Geotechnical Consultant, MWH Chile, (2) Senior geotechnical Consultant, CMGI Consultants (3) Geotechnical Consultant, formerly at Arcadis Abstract An extremely high and frequent seismic activity coincides in Chile with the existence of numerous tailings dams associated to the copper industry. In the country there is a history of tailings dam failures since the early XX century and up to today. Nevertheless since the decade of 1960 there have been a growing number of new large tailings dams that have had a very good performance even when subjected to very strong earthquakes. The paper summarizes the instructive history of failures as well as of successes of the newly designed tailings dams and particularly of the sand tailings dams. Different aspects of the main new sand tailings dams such as the design criteria, tailings sand characteristics under high confining stresses are discussed. These aspects are complemented with information on major earthquakes occurred in Chile in the last years, especially of El Maule Earthquake of Magnitude 8.8 of February 27, 2010 and the location of main tailings dams in the zones impacted by this earthquake. Finally, discussions are included with regard general seismic performance of tailings sand dams, seismic deformations, and seismic instrumentation including dams in operation and dams already inactive. Keywords: Tailings dams, Seismic behavior, Sand dams, Tailings sands, Dynamic properties of sands. -

The delayed aftershocks of the Illapel Earthquake Mw 8.3, 2015, Chile Franco Lema1 and Mahesh Shrivastava1,2 1Departamento de Ciencias Geológicas, Universidad Católica del Norte, Antofagasta, Chile ([email protected]) 2National Research Center for Integrated Natural Disaster Management, Santiago, Chile ([email protected]) The delayed aftershocks 2018 Mw 6.2 on April 10 and Mw 5.8 on Sept 1 and 2019 Mw 6.7 on January 20, Mw 6.4 on June 14, and Mw 6.2 on November 4, associated with the Mw 8.3 2015 Illapel Earthquake occurred in the central Chile. The seismic source of this earthquake has been studied with the GPS, InSAR and tide gauge network. Although there are several studies performed to characterize the robust aftershocks and the variations in the field of deformation induced by the megathrust, but there are still aspects to be elucidated of the relationship between the transfer of stresses from the interface between plates towards delayed aftershocks with the crustal structures with seismogenic potential. Therefore, the principal objective of this study is to understand how the stress transfer induced by the 2015 Illapel earthquake of the heterogeneous rupture mechanism to intermediate-deep or crustal earthquakes. For this, coulomb stress changes from finite fault model of the Illapel earthquake and with the biggest aftershocks in year 2015 are used. These cumulative stress pattern provides substantial evidences for the delayed aftershocks in this region. -
