Velocidad relativa entre las placas del Caribe y suramérica a partir de observaciones dentro del sistema de posicionamiento global (GPS) en el norte de Venezuela

Comparison of Global Positioning System (GPS) observations made in 1994 and 1999 in north-central and northeastern Venezuela and the southern Caribbean region indicate that the Caribbean plate, along its southern boundary, slips at a rate of 20.5±2mm/yr in the N84°±2°E direction relative to the South American plate. Eighty per cent of this dextral slip is contained within an 80km wide shear zone centered approximately on the nearly east-west striking El Pilar-San Sebastián fault system along the northern Venezuelan coast.
