Data Release for the 2018 U.S. Geological Survey–California Geological Survey Fault-Imaging Surveys Across the Hollywood and Santa Monica Faults, Los Angeles County, California

Metadata Updated: October 29, 2025

We acquired multiple types of controlled-source seismic data across the Hollywood Fault in Hollywood, Calif., and the Santa Monica Fault in Beverly Hills, Calif., in May and June of 2018. We acquired two separate profiles across the Hollywood Fault, and from those data we can evaluate multiple seismic datasets and calculate seismic models including guided-wave data, tomographic VP data, tomographic VS data, VP/VS and Poisson's ratio models derived from tomographic VP and VS data, Rayleigh-wave-based VS models, Love-wave-based VS models, VP/Vs and Poisson's ratio models (derived from combinations of tomographic-based VP and surface-wave-based VS models), P-wave reflection images, and S-wave reflection images. All of these data and derived models help delineate near-surface faulting. For the Santa Monica Fault in Beverly Hills, we acquired guided-wave data along Lasky Drive between Moreno Drive and South Santa Monica Boulevard. We used two separate source locations (SP1 and SP2) to generate the guided-wave data. SP1 was more distant from the recording array and the data have a poor signal-to-noise ratio. SP2 was closer to the recording array and this source generated stronger guided waves. The Beverly Hills guided-wave data can also be used to help delineate near-surface faulting in that area.
