Figure F7. East-west seismic section through Site 1048. A listric normal fault west of Site 1048 soles into the proto-décollement zone. A second listric normal fault (below arrow) is near the deformation front of the prism and strikes parallel to the front. Circled letters A and B indicate prominent in-sequence thrust faults. Note the steeply dipping reverse faults above the frontal thrust ramp. Figure modified from Teas (1998).
