Abstract

The northern Hispaniola offshore margin records the active collision between the Bahamas Banks and island arc. This collision is associated to the occurrence of numerous earthquakes that caused significant damages in the northern coast of the island. The NORCARIBE cruise carried out in 2013 combined the systematic acquisition of geophysical data in the whole collisional margin, mainly focused in Dominican Republic, providing continuous and high resolution information. This new information has allowed to study with more detail the along- and across-strike structure of the collisional margin characterized by the Hispaniola trench and the Northern Deformed Belt. This compressive margin shows a N-verging imbricate structure segmented along strike by transfer zones limiting the maximum fault length. There are numerous evidences of active deformation that have to be considered in future studies on the seismic and tsunamigenic assessment in the region, as well as for the assessment on marine resources and development planning of Dominican Republic.
