Sismo de Capellades 01 diciembre 2016, Cartago, Costa Rica
(REVISTA GEOGRÁFICA DE AMÉRICA CENTRAL, 2018)
En este trabajo se hace una descripción de la fuente sísmica del sismo de Capellades, provincia de Cartago, Costa Rica, del 1 de diciembre de 2016, 00:25:20 hora UTC. Se estudian los parámetros de la fuente, centroide, ...
A brittle failure model for long-period seismic events recorded at Turrialba Volcano, Costa Rica
(American Geophysical Union, 2015-01-30)
A temporary seismic network, consisting of 23 broadband and six short-period stations, wasinstalled in a dense network at Turrialba Volcano, Costa Rica, between 8 March and 4 May 2011. During thistime 513 long-period (LP) ...
Nicoya earthquake rupture anticipated by geodetic measurement of the locked plate interface
(Nature Research, 2013-12-22)
The Nicoya Peninsula in Costa Rica is one of the few places on Earth where the seismically active plate interface of a subduction zone is directly overlaid by land rather than ocean. At this plate interface, large megathrust ...
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 ...
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 ...
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 ...
Constraints on upper mantle anisotropy surrounding the Cocos slab from SK(K)S splitting
(American Geophysical Union, 2010-06-24)
SKS and SKKS splitting observations are used to constrain the pattern of mantle flow
in the Central American subduction zone beneath Costa Rica and Nicaragua. After
removing the effects of shallow wedge anisotropy on ...
Crustal Velocity Anomalies in Costa Rica from Ambient Noise Tomography
(Springer Nature, 2019-08-24)
We derive group velocity maps for crustal Rayleigh waves across Costa Rica and corresponding 3-D shear-wave velocity structure from ambient noise cross-correlations between 56 seismic broadband stations. The daily inter-station ...
Monitoring transient changes within overpressured regions of subduction zones using ambient seismic noise
(American Association for the Advancement of Sciences (AAAS), 2016)
In subduction zones, elevated pore fluid pressure, generally linked to metamorphic dehydration reactions, has a profound influence on the mechanical behavior of the plate interface and forearc crust through its control on ...
Yield estimates for the six North Korean nuclear tests from teleseismic P wave modeling and intercorrelation of P and Pn recordings
(AGU Advancing Earth and Space Sciences, 2019)
The yields of the six declared underground nuclear tests at the North Korean test site are estimated using high-frequency teleseismic P wave amplitude modeling and waveform equalization of short-period teleseismic P waves ...
