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 ...
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 ...
