Crustal seismicity in the Andean Precordillera of Argentina using seismic broadband data
(2020)
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, ...
Seismic anisotropy in southern Costa Rica confirms upper mantle flow from the Pacific to the Caribbean
(2020-09-04)
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, ...
Continental and oceanic crustal structure of the Pampean flat slab region, western Argentina, using receiver function analysis: New high-resolution results
(2011)
The Pampean flat slab of central Chile and Argentina (30◦–32◦S) has strongly influenced Cenozoic tectonics in western Argentina, which contains both the thick-skinned, basementcored uplifts of the Sierras Pampeanas and the ...
Neotectóncia de la Falla Cipreses, Costa Rica
(2019)
La falla Cipreses se localiza en la parte central de Costa Rica, en la zona más poblada del país. En esta investigación se analiza esta falla a partir de aspectos geomorfológicos, geológicos ...
Analysis of Seismic Activity near Theodore Roosevelt Dam, Arizona, during the Occupation of the EarthScope/USArray Transportable Array
(2012)
Rate and distribution of seismic activity are important indicators of the overall state of tectonic stress within a region. In regions characterized by low levels of seismicity, active fault surfaces are rarely visible at ...
Lithospheric Structure of the Pampean Flat Slab Region from Double-Difference Tomography
(2019)
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 ...
El Sistema de Falla Navarro: desplazamientos izquierdos a lo largo del Cinturón Deformado del Centro de Costa Rica
The Navarro fault system: Left-lateral displacements along the central Costa Rica deformed belt
(2016)
En este estudio se define el sistema de falla Navarro con base en observaciones geológicas, geomorfológicas y sismológicas. Este sistema de falla está localizado entre las estribaciones norte de la cordillera de Talamanca ...
The National Seismological Network of Costa Rica (RSN): An Overview and Recent Developments
(2018-03)
The National Seismological Network of Costa Rica (RSN) is a joint effort between the University of Costa Rica (UCR) and the Costa Rican Institute of Electricity (ICE). In this article, we briefly describe its history, ...
Actividad sísmica percibida en Costa Rica durante el 2017
Felt seismicity in Costa Rica during 2017
(2018)
Durante el 2017 la Red Sismológica Nacional (RSN: UCR-ICE) localizó 2755 sismos y reportó 216 eventos sentidos por la población, incluyendo cuatro sismos relevantes con magnitudes (Mw) de entre 5,5 y 6,3. La mayoría (91%) ...
Sismicidad registrada por la RSN en el 2016
(2017)
During 2016, the National Seismological Network (RSN: UCR-ICE) registered 4594 earthquakes and reported 210 felt events. There were 13 significant earthquakes with magnitude Mw > 5.0. The majority (86%) of felt earthquakes ...
