On 11 August 2012, two destructive shallow earthquakes Mw=6.4 and
Mw=6.2 occurred within distance of about 6 km and time lag of 11
minutes in Northwestern Iran between the small cities of Ahar and
Varzeghan with no previously well known active fault or significant
seismicity.

Extending urban seismic risk assessment to open spaces for the 2011 Lorca earthquake scenario
We extend the conventional seismic risk assessment approach to open spaces in the 2011 Lorca earthquake scenario. Conventional approaches to seismic risk provide estimates of damaged buildings mainly related to structural failure. The damage related to the production of debris in damaged buildings and its spread in the surrounding space receives a secondary role. However, in many cases, this secondary damage is of prime importance.
Assessment of ground deformation and seismicity in two areas of intense hydrocarbon production in the Argentinian Patagonia
The exploitation of both conventional and unconventional hydrocarbons may lead to still not well-known environmental consequences such as ground deformation and induced/triggered seismicity. Identifying and characterizing these effects is fundamental for prevention or mitigation purposes, especially when they impact populated areas.
Assessing Building Habitability after an Earthquake Using Building Typology and Damage Grade. Application in Lorca, Spain
The present study proposes a statistical methodology to rate the habitability of different types of buildings after an earthquake. The first step was to rank variables that affect the vulnerability of a building and formulate a statistical study with a discrimination index that makes it possible to identify buildings as habitable or non-habitable.
Analysis of the 2014 Mw 7.3 Papanoa (Mexico) Earthquake: Implications for Seismic Hazard Assessment
We analyze the 2014 Papanoa seismic series, located in the Guerrero, Mexico, subduction interface. First, Coulomb failure stress changes because of the mainshock, and the two largest aftershocks are calculated along the interface. The location of aftershock epicenters largely coincides with areas showing positive stress changes.
