Map of the Northeastern Caribbean: topography is in shades of green and bathymetry in shades of blue. Fault traces are shown as lines with the following descriptions: barbed=thrust fault; solid=strike-slip fault with arrows showing relative direction of motion; black and white=normal fault. Faults outlined in red have a potential to generate a large earthquake.
