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 ...
Coda wave attenuation in the Parecis Basin, Amazon Craton, Brazil: sensitivity to basement depth
(Springer, 2011)
Small local earthquakes from two aftershock sequences in Porto dos Gaúchos, Amazon
craton—Brazil, were used to estimate the coda wave attenuation in the frequency band of 1 to 24 Hz. The time-domain coda-decay method of ...
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 ...
Estimating tsunami potential of earthquakes in the Sumatra-Andaman region based on broadband seismograms in India
(Universidad Nacional, Costa Rica., 2012)
In this paper, we report that the ratio of broadband energy (0.01–2 Hz) to highfrequency energy (0.3–2 Hz), Er, estimated from regional seismograms of India, might be a useful parameter in estimating tsunami potential of ...
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 ...
Earthquake magnitude calculation without saturation from the scaling of peak ground displacement
(Geophysical Research Letters, 2015-06-02)
GPS instruments are noninertial and directly measure displacements with respect to a global reference frame, while inertial sensors are affected by systematic offsets—primarily tilting—that adversely impact integration to ...
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 ...
Deslizamientos provocados por el terremoto de Cinchona de 2009, Costa Rica
(Universidad Nacional, Costa Rica., 2013)
El 8 de enero del 2009 ocurrió un sismo que generó una gran cantidad de deslizamientos, los cuales
fueron la causa de severos daños ambientales y sociales. La nubosidad de la zona solo permitió hacer mapas aproximados del ...
