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 ...
Seismogenic zone structure beneath the Nicoya Peninsula, Costa Rica, from three-dimensional local earthquake P- and S-wave tomography
(Geophysical Journal International, 2006)
The subduction plate interface along the Nicoya Peninsula, Costa Rica, generates damaging large (Mw > 7.5) earthquakes. We present hypocenters and 3-D seismic velocity models (VP and VP/VS) calculated using simultaneous ...
A Creep Event on the Shallow Interface of the Nicoya Peninsula, Costa Rica Seismogenic Zone

Summary of the paper "A Creep Event on the Shallow Interface of the Nicoya Peninsula, Costa Rica Seismogenic Zone"
Crustal structure along the southern Central American volcanic front
(American Geophysical Union, 2008-08-20)
Subduction alters continents several ways, including accretion, magmatic addition, mantle wedge serpentinization, and crustal differentiation. These changes affect seismic velocities, so characterizing upper plate crust ...
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 ...
Seismogenic zone structure along the Middle America Trench, Nicoya Peninsula, Costa Rica, from 3D local earthquake tomography
(American Geophysical Union, 2004)
Resumen de la ponencia "Estructura de la zona sismogénica a lo largo de la Fosa Mesoamericana, Nicoya Península, Costa Rica, a partir de tomografía sísmica local 3D"
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 ...
