A Constrained 3D Density Model of the Upper Crust from Gravity Data Interpretation for Central Costa Rica
Lücke Castro, Oscar H.; Götze, Hans-Jürgen; Alvarado Induni, Guillermo E. (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 ... -
Density structure and geometry of the Costa Rican subduction zone from 3-D gravity modeling and local earthquake data
Lücke Castro, Oscar H.; Arroyo Hidalgo, Ivonne Gabriela (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 ... -
Estructura del cono piroclástico Pasquí a partir de interpretación indirecta de datos de gravedad
Gutiérrez, Amalia; Solano Monge, Juan Pablo; Argüello Sáenz, Alejandro; Rivera Romero, Federico; Lücke Castro, Oscar H. (2019-06-01)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 ... -
Formación Bagaces: caracterización de sus unidades para la identificación de depósitos y litofacies
Solano Monge, Juan Pablo; Denyer Chavarría, Percy; Pérez Fernández, Wendy; Lücke Castro, Oscar H.; Madrigal Quesada, María Del Pilar (2019-06-01)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 ... -
Moho structure of Central America based on three-dimensional lithospheric density modelling of satellite-derived gravity data
Lücke Castro, Oscar H. (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 ... -
State of static stress on the Costa Rican Cocos-Caribbean plate interface: mechanical interpretation for the origin of asperities on the seismogenic zone
Lücke Castro, Oscar H. (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 ... -
The seismically active Andean and Central American margins: Can satellite gravity map lithospheric structures?
Köther, Nils; Götze, Hans-Jürgen; Gutknecht, Benjamin D.; Jahr, Thomas; Jentzsch, Gerhard; Lücke Castro, Oscar H.; Mahatsente, Rezene; Sharma, Reka; Zeumann, Stephanie (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 ...
