Density structure and geometry of the Costa Rican subduction zone from 3-D gravity modeling and local earthquake data
The eastern part of the oceanic Cocos Plate presents a heterogeneous crustal structure due to diverse origins and ages as well as plate-hot spot interactions which originated the Cocos Ridge, a structure that converges ...
The seismically active Andean and Central American margins: Can satellite gravity map lithospheric structures?
The spatial resolution and quality of geopotential models (EGM2008, EIGEN-5C, ITG-GRACE03s, and GOCO-01s) have been assessed as applied to lithospheric structure of the Andean and Central American subduction zones. For the ...
State of static stress on the Costa Rican Cocos-Caribbean plate interface: mechanical interpretation for the origin of asperities on the seismogenic zone
Estado de esfuerzos estáticos en la interface de placas coco-caribe en Costa Rica: interpretación mecánica para el origen de asperezas en la zona sismogénica
The forearc region along the Central American Subduction Zone shows a series of trench-parallel posi-tive gravity anomalies with corresponding gravity lows along the trench and toward the coast. These features extend from ...
Moho structure of Central America based on three-dimensional lithospheric density modelling of satellite-derived gravity data
The Central American isthmus hosts a highly variable Moho structure due to the diverse origin and composition of the crustal basement and the influence of large-scale neotectonic processes. Gravity data from the combined ...
A Constrained 3D Density Model of the Upper Crust from Gravity Data Interpretation for Central Costa Rica
The map of complete Bouguer anomaly of Costa Rica shows an elongated NW-SE trending gravity low in the central region. This gravity low coincides with the geographical region known as the Cordillera Volcánica Central. It ...
