High-resolution active-source seismic data acquired near strong-motion recording stations (NSMP 1849 and NSMP 1870) at the Veterans Affairs Medical Center, Menlo Park, San Mateo County, California

On August 24, 2021, the U.S. Geological Survey conducted a high-resolution seismic survey between two strong-motion recording stations located at the Veterans Affairs Medical Center (VAMC) in the City of Menlo Park, San Mateo County, California. The stations are National Strong Motion Project Station (NSMP) 1849 in VAMC building 332 and NSMP Station 1870 in VAMC building 334. The primary goals of the seismic survey are to better understand the potential for amplified ground shaking, to evaluate lateral variability in shear-wave velocity, and to calculate time-averaged shear-wave velocity in the upper 30 m of the subsurface (VS30) at this site using refraction tomography and multichannel analysis of surface waves (MASW) methods.
