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 ... -
Monitoreo geodésico de una Brecha Sísmica Madura: Nicoya, Costa Rica
Protti, Marino; González, Victor (Universidad Nacional, Costa Rica, 2002-10)Una brecha sísmica existe bajo y frente a la Península de Nicoya en el noroeste de Costa Rica. Esta brecha es un segmento de la zona de subducción de Centroamérica donde la placa del Coco se introduce por debajo de la ... -
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 ... -
NICOYA, COSTA RICA, TRANS-PENINSULA GPS EXPERIMENT AND INTER-PLATE COUPLING
Iinuma, Takeshi; Protti, Marino; Obana, Koichiro; Miyazaki, Shinichi; González, Victor; Van der Laat, Rodolfo; Kato, Teruyuki; Kaneda, Yoshiyuki; Hernández, Enrique (2003-06-30)Since 2001, a GPS observation project has been carried out on the Nicoya Peninsula, Costa Rica. Costa Rica is located on the western margin of the Caribbean plate, and the Cocos plate is subducting under the Caribbean plate ... -
