Carbo 2005 <p>There is renewed interest in studying the active and complex northeastern Caribbean plate boundary to better understand subduction zone processes and for earthquake and tsunami hazard assessments [e.g.,<span>&nbsp;</span><i>ten Brink and Lin</i>, 2004;<span>&nbsp;</span><i>ten Brink et al</i>., 2004;<span>&nbsp;</span><i>Grindlay et al</i>., 2005]. To study the active tectonics of this plate boundary, the GEOPRICO-DO (Geological, Puerto Rico-Dominican) marine geophysical cruise, carried out between 28 March and 17 April 2005 (Figure 1), studied the active tectonics of this plate boundary.</p><p>Initial findings from the cruise have revealed a large underwater landslide, and active faults on the seafloor (Figures 2a and 2c). These findings indicate that the islands within this region face a high risk from tsunami hazards, and that local governments should be alerted in order to develop and coordinate possible mitigation strategies.</p> application/pdf 10.1029/2005EO510002 en American Geophysical Union Survey explores active tectonics in northeastern Caribbean article
