Mechanics of back arc deformation in Costa Rica: Evidence from an aftershock study of the April 22, 1991, Valle de la Estrella, Costa Rica, earthquake (Mw=7.7)
(American Geophysical Union, 1994-10)
The April 22, 1991, Mw=7.7 Valle de la Estrella, Costa Rica, earthquake represents back arc thrusting of the Caribbean plate beneath the Panama block along the North Panama Thrust Belt. Large back arc thrusting events are ...
Seismic cycle and plate margin deformation in Costa Rica: GPS observations from 1994 to 1997
(American Geophysical Union, 1999-12-10)
Global Positioning System (GPS) observations in Costa Rica from 1994 to 1997 reveal a complex pattern of motion consistent with the superposition of seismic cycle and secular
plate margin deformation. In the south, velocity ...
