(2016-12)
El Sismo de Capellades del 30 de noviembre del 2016 (Mw 5,5) se originó en la parte intermedia entre los macizos volcánicos del Irazú y Turrialba, a una profundidad bastante somera. Ha sido ...
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, ...
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 ...
Lithospheric structure of Pampean Flat Slab (latitude 30-33°s) and Northern Costa Rica (latitude 9-11°n) Subduction Zones
(2011)
The Pampean flat slab subduction in west-central Argentina (latitude 30-33S) and the steeply dipping Northern Costa Rica subduction zone (latitude 9-11N) show significant along-trench variations in both the subducting and ...
Geoquímica ambiental de las cuencas de los ríos Machuca, Jesús María y parte de Barranca, provincias de Alajuela y Puntarenas, Costa Rica
(2021)
En las cuencas de los ríos Machuca, Jesús María y parte de Barranca fue realizado un estudio geoquímico prospectivo regional cartográfico, basado en sedimentos fluviales y aguas subterráneas, además de rocas de afloramiento ...
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 ...
