Résumé
Due to the convergence of four major plates (Nazca, South America, Cocos and Caribbean) with a group of minor blocks between Central and South America region, it is a tectonic complex area. These small plates have different relative movements respect to the main Plates. Since 1969 a group of tectonic models including different plate borders and kinematic relationships have been proposed. Nowadays there are several databases with homogeneous quality includingseismicity, topography, CPS and magnetic anomalies. These databases allow building a newgeotectonic model by means o f the integration o f all o f them. We have analyzed the topography,seismicity, actual stress regimes and plate kinematics in order to propose a new geotectonicmodel at the south o f Central America and the northwester o f South America.
