Summary

High-resolution Chirp seismic-reflection data were collected by the U.S. Geological Survey in September 2006 offshore San Francisco, California. Data were collected aboard the R/V Lakota, during field activity L-1-06-SF. Chirp data were collected using an EdgeTech 512 chirp subbottom profiler and recorded with a Triton SB-Logger.

Purpose

This work was funded by the USGS Coastal and Marine Geology Program’s Marine Geohazards project. The high-resolution seismic-reflection profiles provide fault geometry information of the San Gregorio, San Andreas, and Golden Gate faults to be used to update the USGS Quaternary fault database and in shaking hazard models developed by the Working Group for California Earthquake probabilities. Other objectives of the mission were to determine thickness of Holocene sediments and verify surficial mapping based on multibeam with surficial features and sediment cover based on subbottom systems. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.
