Pn-wave observations in Costa Rica
(Universidad Nacional Autónoma de México, 1998-02-18)
Tiempos de arribos, medidos en la Red Sismográfica de Costa Rica, fueron empleados para extraer información sobre la corteza y el manto por debajo de Costa Rica. Datos de tiempos de arribo de la onda P y S de 100 sismos ...
Análisis de la actividad sísmica en Costa Rica durante el 2010 y resumen de los eventos sísmicos más importantes presentados en Costa Rica de 1983 - 2012
(Universidad de Costa Rica, 2014-01)
El objetivo de este trabajo es analizar la actividad sísmica registrada por la red sismográfica del OVSICORI-UNA en el año 2010; además de recopilar información de los sismos más importantes sentidos por la población del ...
The intraplate Porto dos Gaúchos seismic zone in the Amazon craton — Brazil
(Elsevier, 2009-01-15)
The largest earthquake observed in the stable continental interior of the South American plate occurred in Serra do Tombador, Mato Grosso state — Brazil, on January 31, 1955 with a magnitude of 6.2 mb. Since then no other ...
Constraints on the sulfur subduction cycle in Central America from sulfur isotope compositions of volcanic gases
(European Association of Geochemistry, 2022-01-20)
The sulfur cycle at convergent margins remains poorly constrained yet is fundamentally important for understanding the redox state of Earth's reservoirs and the formation of ore deposits. In this study we investigate the ...
The Mw 6.4 Damas, Costa Rica, Earthquake of 20 November 2004: Aftershocks and Slip Distribution
(Seismological Society of America, 2006-08)
The earthquake of 20 November 2004 was located north of Damas Island in the Pacific coast of Costa Rica, within the Costa Rica Deformed Belt. The earthquake was located at 24 km depth and reported with a magnitude (Mw) of ...
Isla del Coco, on Cocos Plate, converges with Isla de San Andrés, on the Caribbean Plate, at 78mm/yr
(Revista de Biologia Tropical, 2012-11)
Isla del Coco is the only land mass of the Cocos Plate that emerges above sea level. This makes it the only place where Cocos Plate motion can be measured using Global Navigation Satellite System (GNSS) monitoring. Global ...
Intensidades macrosísmicas del sismo de Capellades del 30 de noviembre de 2016 (Mw = 5,4) y el contexto sísmico de la región central de Costa Rica
(Universidad Industrial de Santander, 2020-01)
El 30 de noviembre del 2016, a las 18:25 hora local, se generó un sismo que se localizó a 4,4 km al noroeste de Capellades de Alvarado, Cartago, Costa Rica; con una magnitud de Mw = 5,4. De acuerdo con la Escala de ...
Along-strike variability in the seismogenic zone below Nicoya Peninsula, Costa Rica
(American Geophysical Union, 2002)
At the subduction zone in northwestern Costa Rica, the seismogenic zone lies directly beneath the Nicoya Peninsula, allowing for near source seismic studies of earthquake activity. We located 650 earthquakes along the ...
The March 25, 1990 (Mw=7.0, ML=6.8), earthquake at the entrance of the Nicoya Gulf, Costa Rica: Its prior activity, foreshocks, aftershocks, and triggered seismicity
(American Geophysical Union, 1995-10-10)
On March 25, 1990 a large earthquake (Mw = 7.0, ML = 6.8) occurred at the entrance of the Nicoya Gulf, Costa Rica, at 1322:55.6 UTC, producing considerable damage in central Costa Rica and generating much interest about ...
The geometry of the Wadati-Benioff zone under southern Central America and its tectonic significance: results from a high-resolution local seismographic network
(Elsevier, 1994)
We present here a detailed geometry of the Wadati—Benioff zone under Costa Rica, obtained from seismicity recorded by a dense local seismographic network jointly operated by the Costa Rica Volcanological and Seismological ...
