16 vertical array sites in California were characterized using microtremor Horizontal-to-Vertical Spectral Ratio (mHVSR) measurements. At each site, 4 tests were performed in concentric circles to assess spatial and azimuthal variation. The data, resulting from collaboration between UCLA, USC, and the University of Canterbury, is available in the United States Community Shear-Wave Velocity Profile Database.
Use Cases
- Identifying potential site resonances based on HVSR curves
- Investigating spatial variation of ground vibrations based on concentric circle tests
- Assessing consistency of geology based on multiple mHVSR measurements per site
- Predicting seismic site response conditioned on HVSR data
Strengths
- Data from 16 distinct vertical array sites
- 4 tests per site in concentric circles for spatial analysis
- Publicly accessible via the United States Community Shear-Wave Velocity Profile Database
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
