We obtain earthquake locations and a detailed three-dimensional velocity model of the flat slab subduction zone in west-central Argentina (latitudes: 32-30°S and longitudes: 70-66°W) using a regional-scale doubledifference ...

Entre agosto y noviembre del 2018 ocurrió una secuencia de sismos en el golfo Dulce, cerca de la ciudad de Golfito, al sureste de Costa Rica. El sismo principal tuvo una magnitud momento (Mw) 6.1 y fue sentido en Costa ...

Costa Rica se ubica en el límite entre varias placas tectónicas, por lo que los sismos son comunes y parte de la vida cotidiana de sus habitantes. La Red Sismológica Nacional (RSN), con sede ...

Past studies of southern Costa Rica have generated a multitude of tectonic scenarios to account for different data sets. Flat slabs, detached slabs, and slab windows have been proposed to address the uplift of the Cordillera ...

Surrounded by subducting slabs and continental keels, the upper mantle of the Pacific is largely prevented from mixing with surrounding areas. One possible outlet is beneath the southern part of the Central American isthmus, ...

In this study, we analyze 100 crustal Precordilleran earthquakes recorded in 2008 and 2009 by 52 broadband seismic stations from the SIEMBRA and ESP, two temporary experiments deployed in the Pampean flat slab region, ...

El Caribe Sur de Costa Rica fue en 1991 el escenario del último gran terremoto (Mw 7,7) entre la placa Caribe y la microplaca de Panamá. Pese a la alta sismicidad y avances en la cobertura de las redes sísmicas, esa zona ...

Costa Rica is a seismically active region located in a subduction zone. Combining earthquake data from the National Seismological Network and several Central American catalogs from 1522 to 2020, we present a new estimation ...

We analyze the performance of a prototype earthquake early warning system deployed at the National Seismological Network of Costa Rica in collaboration with the Swiss Seismological Service by presenting the real-time ...

A noticeable decrease in seismic noise was registered worldwide during the lockdown measures implemented in 2020 to prevent the spread of COVID-19. In Central America, strong lockdown measures started during March of ...
