Fine-Tuning the Seismic Potential of the Nicoya Gap in NW Costa Rica
(American Geophysical Union, 2007-05-22)
The Nicoya seismic gap is a subduction segment along the Middle American Trench where the Cocos plate subducts under the Caribbean plate. This seismic gap, located under the Nicoya Peninsula in northwestern Costa Rica, has ...
A Creep Event on the Shallow Interface of the Nicoya Peninsula, Costa Rica Seismogenic Zone
(American Geophysical Union, 2004)
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 ...
Active Thrusting in the Inner Fore arc of Middle America, Costa Rica
(American Geophysical Union, 2004)
Summary of the paper "Active Thrusting in the Inner Fore arc of Middle America, Costa Rica"
Tomographic evidence for a subducted seamount beneath the Gulf of Nicoya, Costa Rica: The cause of the 1990 Mw = 7.0 Gulf of Nicoya earthquake
(American Geophysical Union, 2002-04-26)
Tomographic images constrain the existence of a subducted seamount beneath the Gulf of Nicoya, Costa Rica. The subducted seamount is found at a depth of 30 km within the rupture area of the March 25, 1990, Mw = 7.0 Gulf ...
An improved P-wave velocity reference model for Costa Rica
(Universidad Nacional Autónoma de México, 2001-01-01)
Derivamos un modelo de velocidad unidimensional para la onda P en Costa Rica, el cual puede servir en la rutina de localización de eventos sísmicos y como modelo de referencia para tomografía en 3 dimensiones. La inversión ...
The intraplate Porto dos Gaúchos seismic zone in the Amazon craton — Brazil
(Elsevier, 2009-01-15)
The largest earthquake observed in the stable continental interior of the South American plate occurred in Serra do Tombador, Mato Grosso state — Brazil, on January 31, 1955 with a magnitude of 6.2 mb. Since then no other ...
International geosciences field research with undergraduate students: Three models for experiential learning projects investigating active tectonics of the Nicoya Peninsula, Costa Rica
(Geological Society of America, 2009)
International field experiences offer exceptional opportunities for effective student
learning in the geosciences. Over the 10 yr period between 1998 and 2008, more than 40
undergraduate students from 14 institutions ...
The Mw 6.4 Damas, Costa Rica, Earthquake of 20 November 2004: Aftershocks and Slip Distribution
(Seismological Society of America, 2006-08)
The earthquake of 20 November 2004 was located north of Damas Island in the Pacific coast of Costa Rica, within the Costa Rica Deformed Belt. The earthquake was located at 24 km depth and reported with a magnitude (Mw) of ...
