Microtremor Horizontal-to-Vertical Spectral Ratio (mHVSR) Data Collection at Brentwood, 2022

The Brentwood Veteran Affairs (VA) Complex is situated near the Santa Monica mountains within the West Los Angeles area. This area experiences seismic activity due to its proximity to the Santa Monica fault and other faults within the LAB. In an effort to better understand the geology and also aid in future site response model development, microtremor Horizontal-to-Vertical Spectral Ratio (mHVSR) surveys were performed specifically near vertical arrays. Collaborative research between the University of Southern California (USC) and the University of California, Los Angeles (UCLA) have performed mHVSR surveys at 10 areas within the Heroes golf course area of the VA complex. The HVSR spectra developed using this dataset may be accessed in the United States Community Shear-Wave Velocity (VS) Profile Database (PDB) (https://vspdb.org). This work was supported by the Sonny Astani Department of Civil and Environmental Engineering at the Viterbi School of Engineering, University of Southern California(USC).
