AbstractCommon depth point seismic data, collected as part of a hydrocarbon exploration program in the Fraser River delta has been interpreted to map the depth to bedrock, which coincides with the Pleistocene-Tertiary unconformity. A structure map of the surface shows northwest-trending highs and lows, ranging in depth from 200 to 1000 m. The development of a bedrock map forms a key component of the geological and geophysical framework relevant to geotechnical investigations focussing on the ground response to earthquake shaking.
