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 ...
Stratified flow past a mesoscale mountain range
(2000)
Se investiga el efecto de la interacción entre el viento y una cordillera aislada orientada de forma perpendicular al flujo de referencia. La simulación numérica tridimensional muestra que para el régimen de viento escogido ...
Importancia de los estudios geofísicos y tectónicos como herramientas para lograr una mejor comprensión de la vulnerabilidad hidrogeológica en los rellenos sanitarios de Costa Rica.
(2015-11-09)
Este documento se basa principalmente en la revisión y el análisis de las actuales disposiciones
técnico/científicas emitidas por el Servicio Nacional de Aguas Subterráneas Riego y Avenamiento (SENARA) de
Costa Rica, las ...
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 ...
Origin of plagiogranites in oceanic complexes: A case study of the Nicoya and Santa Elena terranes, Costa Rica
(2016)
The origin of minor leucocratic intrusions known as “plagiogranites” in oceanic complexes dominated by basaltic compositions have been debated in the literature. Here we use well preserved plagiogranites within the contrasting ...
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 ...
Procesos sísmicos y volcánicos en los siglos XVII Y XVIII: Casos específicos de América Central
Seismic and volcanic processes in the seventeenth and eighteenth centuries: specific cases of Central America.
(2016)
El objetivo de este trabajo es mostrar cómo el encuentro entre la Historia y la Geología abren conjuntamente una ventana hacia una mejor com-prensión de las implicaciones de las manifestaciones geológicas, tales como el ...
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 ...
A melt-focusing zone in the lithospheric mantle preserved in the Santa Elena Ophiolite, Costa Rica
(2015-08-01)
The Santa Elena Ophiolite in Costa Rica is composed of a well-preserved fragment of the lithospheric mantle that formed along a paleo-spreading center. Within its exposed architecture, this ophiolite records a deep section ...
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 ...
