  The contact between the Caribbean and North American plates is a tectonically
complicated boundary where the deformation is accommodated in north and south
of Hispaniola by the Enriquillo Plantain Garden and Septentrional Oriente Fault
Zones. We present a crustal and tectonic study of the Northeastern Caribbean
Plate Boundary from wide-angle seismic data acquired during the GEOPRICO-DO and
CARIBE NORTE surveys, showing two transects crossing, from north to south,
North American Plate, Bahamas Platform, central Hispaniola and Caribbean Plate.
The results presented include two 2D P wave velocity models of 425 km and 200
km long oriented NNE SSW and ENE SSW, respectively, obtained by the travel time
forward and inverse modeling of the WAS data. Our study defines that the
contact between Bahamas Platform, North American Plate and Hispaniola
corresponds to oblique subduction with the Moho dipping 11 in the NNE SSW
direction. Furthermore, in the south, our results reveal the existence of an
anomalous deep-reaching zone of lateral velocity variation in the mantle that
could be associated with EPGFZ and a possible detached oceanic slab from NOAM
that could explain the deep seismicity in the region.
