    • Constraints on inner forearc deformation from balanced cross sections, Fila Costen˜ a thrust belt, Costa Rica 

      Sitchler, Jason C.; Fisher, Donald M.; Gardner, Thomas W.; Protti, Marino (American Geophysical Union, 2007-12-21)
      The Fila Costeña thrust belt in the forearc of Costa Rica is accommodating a significant portion of the convergence of the Cocos plate and Panama microplate. Geologic mapping of the thrust belt depicts a duplex with three ...

    • 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 ...

    • Middle to Late Miocene Contractional Deformation in Costa Rica Triggered by Plate Geodynamics 

      Mescua, José Francisco; Porras, Hernán; Durán, Patrick; Giambiagi, Laura; Maarten de Moor, J; Cascante, Monserrat; Protti, Marino; Poblete, Fernando (AGU Publications, 2017-12-11)
      Contractional deformation in Costa Rica is usually attributed to the subduction of the aseismic Cocos Ridge. In this work, we review the evidences for contraction in the middle to late Miocene, prior to the arrival of the ...

    • 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 ...
