    • Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity L-4-90-SC

    Metadata Updated: January 6, 2026

    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.
