Rupture processes of the 2012 September 5 Mw 7.6 Nicoya, Costa Rica earthquake constrained by improved geodetic and seismological observations
(2015-08-17)
On 2012 September 5, the anticipated interplate thrust earthquake ruptured beneath the Nicoya peninsula in northwestern Costa Rica close to the Middle America trench, with a magnitude Mw 7.6. Extensive co-seismic observations ...
The Sao Vicente earthquake of 2008 April and seismicity in the continental shelf off SE Brazil: further evidence for flexural stresses
(Wiley-Blackwell, 2011-12-01)
The continental margin and shelf of most stable intraplate regions tend to be relatively more seismically active than the continental interior. In the southeast continental margin of Brazil, a seismic zone extends from Rio ...
Rupture process of the April 24, 2017, M-w 6.9 Valparaiso earthquake from the joint inversion of teleseismic body waves and near-field data
(Elsevier, 2018-06)
The central Chilean margin (32 degrees-33 degrees S) is characterized by the subduction of the Juan Fernandez Ridge (JFR) beneath the continental South American plate. The JFR corresponds to a hotspot track composed by ...
Enjambres sísmicos en la placa Caribe y la microplaca de Panamá disparados por el terremoto de Nicoya (7,6 Mw) del 5 de septiembre del 2012
(2014)
La sismicidad disparada remotamente que ocurre a distancias superiores a 1-2 veces la longitud de la falla, parece ser un fenómeno frecuente que se ha presentado en Costa Rica luego de sismos de magnitud mayor a 7,0 Mw ...
Sismicidad en Costa Rica durante el 2015
(2016)
Durante el 2015 la Red Sismológica Nacional (RSN: UCR-ICE) localizó 6989 sismos de los cuales 168
fueron sentidos por la población. Se percibieron en Costa Rica 13 sismos con magnitud Mw > 5,0. La mayoría (86%) de los ...

Intraplate earthquake swarm in Belo Jardim, NE Brazil: reactivation of a major Neoproterozoic shear zone (Pernambuco Lineament)
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Intraplate earthquakes in stable continental areas have been explained basically by reactivation of pre-existing zones of weakness, stress concentration, or both. Zones of weakness are usually identified as sites of the ...
Performance of tall buildings in Viña del Mar in the 27 February 2010 offshore Maule, Chile earthquake
(John Wiley, 2011)
After the devastating offshore Maule, Chile earthquake of moment magnitude 8.8 on 27 February 2010, the Los
Angeles Tall Buildings Structural Design Council (LATBSDC) organized a reconnaissance team to visit the
Santiago, ...
