Seafloor Map Image
(Top image) Shaded relief of the new multibeam bathymetry
along the Puerto Rico Trench illuminated from the northwest. Thin contours
indicate bathymetry at 500-m intervals. (Bottom image) Combined bathymetry
map of the multibeam bathymetry data, single-beam bathymetry compilation
around Puerto Rico, Lidar data near shore, and topography of Puerto Rico.
Contour interval is 500 m. Thick barbed white lines denote thrust faults;
thick white lines denote normal faults; thin white line denotes strike-slip
fault; thin black line denotes northern edge of tilted carbonate platform
and southern edge on land; dashed lines indicate head scarp of slope failures;
dotted line indicates debris toe; blue lines indicate fissures in the
seafloor; A - pull-apart basin; B - location of probable extinct mud
volcano observed on backscatter images. Large box and a grey arrow show
location and viewing direction of the figure shown in the tsunami section.
