Aftershocks of the 2012 Mw 7.6 Nicoya, Costa Rica, earthquake and mechanics of the plate interface
(Seismological Society of America (SSA), 2017-05-02)Subduction of the Cocos plate beneath the Nicoya Peninsula, Costa Rica, generates large underthrusting earthquakes with a recurrence interval of about 50 yrs. The most recent of these events occurred on 5 September 2012 ... -
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 ... -
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 ... -
Base computarizada de datos sobre Tectónica y Geología estructural de Centroamerica y el Caribe (Tectobase)
(Universidad de Costa Rica, 1985)Presentación de proyecto de banco computarizado sobre la bibliografía publicada sobre sobre Tectónica y Geología Estructural de Centroamérica y el Caribe (TECTOBASE) -
Coastal Deformation Patterns Along the Nicoya Seismic Gap, Pacific Coast, Costa Rica, Central America
(American Geophysical Union, 2004)Summary of the paper "Coastal Deformation Patterns Along the Nicoya Seismic Gap, Pacific Coast, Costa Rica, Central America" -
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 ... -
Correlation between the age of the subducting Cocos plate and the geometry of the Wadati- Benioff zone under Nicaragua and Costa Rica
(1981-06)This work integrates six tectonic feautures related to the subduction of the Cocos plate under the Caribbean plate along the souhern terninus of the Middle America Trench (Nicaragua and Costa Rica) into a self-consistent ... -
Correlation between the age of the subducting Cocos Plate and the geometry of the Wadati-Benioff zone under Nicaragua and Costa Rica.
(Universidad Nacional, Costa Rica, 1995)High- resolution seismicity data from Costa Rica and southern Nicaragua have been used to image the geometry of the Wadati-Benioff zone under southern Central America. The data include 9,514 events with computed horizontal ... -
Crustal structure along the southern Central American volcanic front
(American Geophysical Union, 2008-08-20)Subduction alters continents several ways, including accretion, magmatic addition, mantle wedge serpentinization, and crustal differentiation. These changes affect seismic velocities, so characterizing upper plate crust ... -
Crustal Thickness Along the Central American Volcanic Arc
(American Geophysical Union, 2004)Resumen de ponencia "Crustal Thickness Along the Central American Volcanic Arc" -
Imaging the Subduction Factory Beneath Central America: The TUCAN Broadband Seismic Experiment
(American Geophysical Union, 2004)Summary of the paper "Imaging the Subduction Factory Beneath Central America: The TOUCAN Broadband Seismic Experiment" -
International geosciences field research with undergraduate students: Three models for experiential learning projects investigating active tectonics of the Nicoya Peninsula, Costa Rica
(Geological Society of America, 2009)International field experiences offer exceptional opportunities for effective student learning in the geosciences. Over the 10 yr period between 1998 and 2008, more than 40 undergraduate students from 14 institutions ... -
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 ... -
Middle to Late Miocene Contractional Deformation in Costa Rica Triggered by Plate Geodynamics
(AGU Publications, 2017-12-11)Contractional deformation in Costa Rica is usually attributed to the subduction of the aseismic Cocos Ridge. In this work, we review the evidences for contraction in the middle to late Miocene, prior to the arrival of the ... -
OVSICORI's Southern Costa Rica Geodynamic Control Network: The opening of a Pandora's Box
(IASPEI, 2016-06-20)Summary of the presentation “OVSICORI's South Costa Rica Geodynamic Control Network: Opening a Pandora's box. Presented at II General Assembly of the Latin America and Caribbean Seismological Commission of IASPEI, Heredia, ... -
Regional characteristics of observable foreshocks
(Seismological Society of America (SSA), 2022)Measures of foreshock occurrence are systematically examined using earthquake catalogs for eight regions (Italy, southern California, northern California, Costa Rica, Onshore Japan, Alaska, Turkey, and Greece) after imposing ... -
Repeating earthquakes record fault weakening and healing in areas of megathrust postseismic slip
(American Association for the Advancement of Sciences (AAAS), 2020)Repeating earthquakes (REs) rupture the same fault patches at different times allowing temporal variations in the mechanical behavior of specific areas of the fault to be interrogated over the earthquake cycle. We study ... -
