High-resolution seismic data acquired at six seismic network recording stations in San Bernardino County, California in 2019
In May 2019, the U.S. Geological Survey acquired high resolution P- and S-wave seismic data near six seismic network recording stations in San Bernardino County, California: Southern California Seismic Network CI.CLT Calelectic, CI.MLS Mira Loma, CI.CJM Cajon Mountain and CI.HLN Highland; California Strong Motion Instrumentation Program station CE.23542; and US National Strong-Motion Network station NP.5326 (Figure 1). The primary goals of the seismic survey were to better understand the potential for amplified ground shaking, to evaluate lateral variability in shear-wave velocity, and to calculate Vs30 at these sites.
We deployed up to 67 DTCC SmartSolo 3-component seismometer systems ("nodes") at 2-m spacing along six linear arrays and collocated P- and S-wave sources at ~1-m offset from the nodes. We generated active-source P-waves using a 3.5-kg sledgehammer and steel plate combination. Active-source S-waves were generated by horizontally striking an aluminum block with a 3.5-kg sledgehammer. SmartSolo nodes are standalone seismometers with 3-component sensors (5-Hz corner frequency and sensitivity of 76.7 volts/meter/second), battery, and built-in GPS to record location and time. The nodes recorded seismic data continuously at a 0.5-ms sampling rate, and shot timing was recorded by GPS event capture hardware to precisely determine the shot times. For some individual surveys, the nodes were buried a few inches below the ground surface to reduce noise. This report provides the metadata needed to utilize the seismic data.
