Sismicidad y marco neotectónico de Costa Rica y Panamá

Abstract

We define the different active tectonic boundaries of the Costa Rica - Panamá region. Specially we refine the different seismogenic zones and the structural characteristics of the Panamá microplate, a small tectonic block enclose between the Cocos, Caribbean, Nazca and South American plates. The tectonic setting of the Limon earthquake was the North Panama Deformed Belt, the northern limit of the Panama microplate. The deformation along this region is proposed to be tectonically controlled by the collision of the Cocos ridge along the southeastern Costa Rican border.
