Seafloor measurement of seismic activity, October 1, 1983-September 30, 1991
The objective of the SEMS project is to gather strong motion earthquake data from offshore oil and gas leasing regions that are seismically active. The principal areas of interest are offshore southern California, in the Southern Bering Sea, and near the Aleutian Islands. One SEMS unit was installed during 1985 in the Beta Field offshore Long Beach, California. The project will eventually emplace and monitor multiple SEMS units in Alaskan waters where the greatest hazards exist. The ultimate product is a set of data which can be used to characterize the response of seafloor sediments to earthquake-induced seismicity. This report describes the design and function of the instrumentation and data recording systems, and discusses potential future plans for SEMS deployment in offshore southwestern Alaska. (ACR)
