Actividad histórica y análisis de la amenaza del volcán Turrialba, Costa Rica
HISTORIC ACTIVITY AND HAZARD ANALYSIS OF TURRIALBA VOLCANO, COSTA RICA
(2015)
The historic activity of Turrialba volcano was studied based on traveler’s reports and newspapers of the
19th century. In 1864-1866, the volcano was in a period of magmatic eruptions which can be subdivided in two stages: ...
Moho structure of Central America based on three-dimensional lithospheric density modelling of satellite-derived gravity data
(2012-05-23)
The Central American isthmus hosts a highly variable Moho structure due to the diverse origin and composition of the crustal basement and the influence of large-scale neotectonic processes. Gravity data from the combined ...
A Constrained 3D Density Model of the Upper Crust from Gravity Data Interpretation for Central Costa Rica
(2010-01-05)
The map of complete Bouguer anomaly of Costa Rica shows an elongated NW-SE trending gravity low in the central region. This gravity low coincides with the geographical region known as the Cordillera Volcánica Central. It ...
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 ...
Deformación sísmica reciente de la Sierra de Pie de Palo, Provincia de San Juan
(2014)
En este trabajo se estudia la actividad sísmica en la sierra de Pie de Palo durante enero 2008 a diciembre 2009. Los datos utilizados fueron registrados por 52 estaciones sismológicas de los experimentos SIEMBRA y ESP. En ...
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 ...
A recent tear in subducting plate explains seismicity and upper mantle structure of southern Costa Rica
(2020-11-12)
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 ...
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, ...
Ciencia ciudadana y herramientas de comunicación en la Red Sismológica Nacional de la Universidad de Costa Rica
(2020-12-16)
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 ...
