The seismically active Andean and Central American margins: Can satellite gravity map lithospheric structures?
(2011-11-17)
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 ...
A Constrained 3D Density Model of the Upper Crust from Gravity Data Interpretation for Central Costa Rica
(2010-01-05)
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 ...

El volcán Irazú presenta, en sus cuadrantes sur y oeste, numerosas estructuras relacionadas con antiguos focos de emisión de lavas y piroclastos fuera de su foco cuspidal. Una serie de estas estructuras se encuentra asociada ...
Density structure and geometry of the Costa Rican subduction zone from 3-D gravity modeling and local earthquake data
(2015-10-29)
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 ...
Moho structure of Central America based on three-dimensional lithospheric density modelling of satellite-derived gravity data
(2012-05-23)
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 ...

La base de la cordillera volcánica de Guanacaste está conformada, en su mayoría, por una potente secuencia de depósitos piroclásticos de edades entre el Mioceno y el Pleistoceno, las cuales corresponden a las formaciones ...
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
(2015-11)
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 ...
