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, ...
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) ...
Constraints on inner forearc deformation from balanced cross sections, Fila Costen˜ a thrust belt, Costa Rica
(American Geophysical Union, 2007-12-21)
The Fila Costeña thrust belt in the forearc of Costa Rica is accommodating a significant portion of the convergence of the Cocos plate and Panama microplate. Geologic mapping of the thrust belt depicts a duplex with three ...
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 ...
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 ...
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 ...
