Constraints on upper mantle anisotropy surrounding the Cocos slab from SK(K)S splitting
Abt, David L.; Fischer, Karen M.; Abers, Geoffrey A.; González, Victor; Strauch, Wilfried; Protti, Marino (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 structure along the southern Central American volcanic front
Mackenzie, Laura; Abers, Geoffroy A.; Fischer, Karen M.; Protti, Marino; González, Victor (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 ... -

Fine-Tuning the Seismic Potential of the Nicoya Gap in NW Costa Rica
González, Victor; Protti, Marino (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 ... -
Nicoya earthquake rupture anticipated by geodetic measurement of the locked plate interface
Protti, Marino; González, Victor; Newman, Andrew; Dixon, Timothy H.; Schwartz, Susan; Marshall, Jeffrey S; Feng, Lujia; Walter, Jacob; Malservisi, Rocco; Owen, Susan E. (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 ... -

Deshon, Heather R.; Schwartz, Susan; Dorman, LeRoy; Newman, Andrew V.; Protti, Marino; González, Victor (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" -
Seismogenic zone structure beneath the Nicoya Peninsula, Costa Rica, from three-dimensional local earthquake P- and S-wave tomography
Deshon, Heather R.; Schwartz, Susan; Newman, Andrew; González, Victor; Protti, Marino; Dorman, LeRoy; Dixon, Timothy; SAMPSON, DANIEL; Flueh, Ernst R. (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 ... -
