An improved P-wave velocity reference model for Costa Rica
(Universidad Nacional Autónoma de México, 2001-01-01)
Derivamos un modelo de velocidad unidimensional para la onda P en Costa Rica, el cual puede servir en la rutina de localización de eventos sísmicos y como modelo de referencia para tomografía en 3 dimensiones. La inversión ...
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 ...
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 ...
Parâmetros de fonte de sismos locais por inversão de formas de ondas
(Sociedade Brasileira de Geofísica, 2010-11)
The main purpose of this work is to invert seismic waveforms in order to obtain moment tensor for two medium size earthquakes detected by OVSICORI-UNA Costa Rica permanent seismic network, occurred in 2004, following the ...
Coda wave attenuation in Mara Rosa seismic zone
(Sociedade Brasileira de Geofísica, 2013-08-26)
Small local earthquakes from aftershock sequence in Mara Rosa, Goiás state, Brazil were used to estimate the coda wave attenuation in the frequency band of 1 to 20 Hz. The time-domain coda-decay method of a single ...
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 ...
