The precision that satellite geodetic data offer, allows us to monitor intraplate areas where the movements of the lithosphere are otherwise imperceptible. In the case of Argentina, most of the neotectonic studies are focused on the Andes, considering the Pampa Region as a stable region and without seismogenic capability. This great plain region is located in the foreland basin eastward from the Pampean Ranges and the cratonic area of the Mesopotamia, in the latitudinal segment of the Nazca Plate sub-horizontal subduction. In this work, the Velocity Model for South America and the Caribbean (VEMOS09) was analyzed as well as the data from 5 GNSS Permanent Stations (PS) with data series longer than 3 years,in order to observe the regional tendency of the velocity field in the Rio de la Plata Craton (RPC).
