Faulting, shallow seismicity and seismic hazard analysis for the Costa Rican Central Valley
(2000)
A seismic hazard map for the Metropolitan Area of San Jose has been elaborated, based on local tectonic and seismic information. The area for the hazard computation covers an area of 20 x 15 km2 and includes the zone where ...
Record of massive upwellings from the Pacific large low shear velocity province
(2016)
Large igneous provinces, as the surface expression of deep mantle processes, play a key role in the evolution of the planet. Here we analyse the geochemical record and timing of the Pacific Ocean Large Igneous Provinces ...
Comparison of Tree Species Sensitivity to High- and Low-Extreme Hydroclimatic Events
(2001-03)
We present here a six-species comparison of tree-ring growth response to
extremes (below the 30th and above the 70th percentile) in temperature, precipitation,
and corresponding streamflow. The species compared are Pinus ...
Atenuación de contaminantes por procesos de sorción en la zona no saturada, en una parcela experimental en el occidente del Valle Central de Costa Rica
(2017-05)
Se realizó un estudio sobre la atenuación de contaminantes con el propósito de determinar las
constantes de reparto entre el suelo y el agua intersticial para una decena de plaguicidas. Las
muestras de suelo fueron ...
La crisis sísmica de Bijagua de Upala (enero a marzo del 2002), Costa Rica
(2002)
En el presente informe se analiza la información sismológica obtenida por los instrumentos sismográficos de la RSN, además de los datos de campo recopilados en la zona, tales como: efectos, daños, evidencias de fallamiento ...
Geología de Turrialba: Una historia de 60 millones de años
(2007)
La historia geológica de Costa Rica es muy compleja y debe enmarcarse dentro de la Teoría de la Tectónica de Placas, según la cual, grandes bloques o placas se mueven unos con respecto de otras, generando un complejo mosaico ...
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 ...
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 ...
