Inset shows map of Central America, Cocos Plate, and Caribbean Plate. The stippled rectangle shows the location of the 3D seismic grid. The longer lines are 2D profiles. Bathymetric map of the Middle America Trench and lower continental slope region off the Nicoya peninsula, Costa Rica. Contour interval is 20 m. Figure 3.
Vertical scale is in two-way traveltime.
Figure 4 . Depth migrated seismic Line CR-20, located in Fig. 2. 3D seismic reflection Line CR3D-48, which crosses Site 1042. Profile is taken from depth-migrated 3D grid and is located near the southeast corner of the grid. At greater depth, the prism appears to be cut by thrust faults.
