Summary

Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in 1990 in the California Continental Borderland (USGS field activity L490SC). In 2021, these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California’s continental margin. MCS data were acquired to support the Southern California Earthquake Hazards project to help mitigate earthquake and tsunami hazards for the Southern California region by improving our understanding of how deformation is distributed (spatially and temporally) in the offshore with respect to the onshore region. The reprocessed dataset enhances the seismic data quality which will be useful for future research on the geomorphic, sedimentary and tectonic history offshore California. These data are intended for science researchers, students, policy makers, and the general public.
