2015 High Resolution Seismic Data Recorded at Six Strong Motion Seismograph Sites in Napa and Solano Counties, California

In May 2015, we acquired high-resolution seismic profiles near six strong motion instruments located in Napa and Solano Counties, California. These strong motion instruments recorded horizontal peak accelerations (PGAs) from 0.329g to 0.611g, which were among the highest recorded in the Napa area during the 24 August 2014 Mw 6.0 South Napa Earthquake. Our goal is to measure the seismic velocities of the underlying geologic material at each strong motion site using P- and S-wave refraction tomography and analysis of surface waves, especially in the upper 30 m of the subsurface.
