A report on the 24 August 2011 Mw 7.0 Contamana, Peru, intermediate-depth earthquake
(Seismological Society of America, 2012-11-01)
The seismic activity in Peru has its origin in the convergence process between the Nazca and the South American plates. Such convergence takes place at an average velocity on the order of 7–8 cm/yr (DeMets et al., 1980; ...
The chilean earthquake and tsunami 2010
(Universidad de Chile, 2012)
The book discusses the Chilean earthquake that occurred on 27 February 2010. It reached a magnitude of 8.8 Mw and had its epicentre in Cobquecura, in the Bío- Bío region. The phenomenon mainly affected central Chile, which ...
Estimation of slip scenarios for megathrust earthquakes: a case study for Peru
(University of California Santa Barbara, 2011-08-13)
The recent 2011 Tohoku-oki earthquake occurred in a region where giant megathrust earthquakes were not expected. This earthquake proved the difficulty to assess seismic hazard mainly based on information from historical ...
The September 19, 2017 Mw 7.1 Puebla-Mexico City Earthquake: Observed Rockfall and Landslide Activity
(2019)
This note documents key observations of slope instability and rockfall activity made by the UNAM-GEER reconnaissance team after the Mw 7.1 Puebla-Mexico City earthquake of September 19, 2017. The investigated sites were ...
Energy Budget of Intermediate-Depth Earthquakes in Northern Chile: Comparison With Shallow Earthquakes and Implications of Rupture Velocity Models Used
(Blackwell Publishing Ltd, 2019)
We calculate well-resolved corner frequencies and radiated energies for a set of 96 earthquakes divided into two clusters located in the same tectonic setting but with different depths in northern Chile. Fifty-three shallow ...
Characterization of historical megathrust earthquake ruptures in South Central Chile using logic tree analysis.
(Universidad de Concepción, Facultad de Ciencias Físicas y Matemáticas., 2023)
Characterizing the spatial distribution of ruptures from historical and recent earthquakes is key to understanding the seismic cycle of large earthquakes in subduction zones, and thus to assessing the potential risks ...
Data collection after the 2010 Maule earthquake in Chile.
(2017)
This article presents an overview of the different processes of data recollection and the analysis that took place during and after the emergency caused by the Mw 8.8 2010 Maule earthquake in central-south Chile. The article ...
Stochastic Generation of Accelerograms for Subduction Earthquakes
(Seismological Society of America, 2016)
The generation of accelerograms using stochastic methods has been a very useful methodology for solving the problem of the lack of appropriate strong-motion records for seismic design. Here, we propose the generation of ...
Seismicity and tectonics
(Earthquake Engineering Research Institute, 2003)
The Southern Peru earthquake of 23 June 2001 resulted from thrust faulting on the boundary between the Nazca and South American plates. In terms of seismic moment release, the Mw (HRV) 8,4 earthquake was arguably the largest ...
Seismic Response of Reinforced Concrete Buildings in Concepcion During the 2010, Maule Earthquake
(2012)
This article describes the response of eight shear wall buildings that experienced severe structural damage in Concepcion during the February 27th, 2010 Chile earthquake. Damaged elements within the lateral forceresisting ...
