Mark Goldman
Hello. I am a geophysicist with the United States Geological Survey, specializing in active-source, land-based seismology. I use a variety of techniques such as refraction tomography, reflection imaging, Vp/Vs measurements, and guided wave data to locate faults in the near subsurface.

High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California
In February 2015, the U.S. Geological Survey conducted a high-resolution seismic survey across the West Napa Fault zone at Hendry Winery in Napa, California (Fig. 1). Geophones were deployed every 3 to 5 meters along a southwest-northeast trend to create an approximately 400-m-long linear array. Data were recorded by two Geometrics Stratavisor NZ-60TM seismographs. Both P-wave and S-wave...
High-resolution seismic data acquired at two seismic recording stations (BK.LIND and BK.KARE) in San Joaquin Valley, California High-resolution seismic data acquired at two seismic recording stations (BK.LIND and BK.KARE) in San Joaquin Valley, California
In November of 2021, the U.S. Geological Survey acquired high-resolution P- and S-wave seismic data at two seismic recording stations in Tulare and Fresno counties, California: Berkeley Digital Seismic Network BK.LIND and BK.KARE. We deployed 60 DTCC SmartSolo 3-component nodal seismometers (“nodes”) at 2-m intervals along a linear array at each seismic recording station. The nodes...

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...
Nodal Seismometer Recordings of Aftershocks of the 5 December 2024 M 7.0 Offshore Cape Mendocino, California Earthquake Nodal Seismometer Recordings of Aftershocks of the 5 December 2024 M 7.0 Offshore Cape Mendocino, California Earthquake
At 10:44:21 local time on December 5, 2024, a M 7.0 earthquake occurred approximately 70 km southwest of Ferndale, California, just west of the Mendocino Triple Junction. Starting the next day, the U.S. Geological Survey deployed nodal seismometers (nodes) in the Eel River Valley, near Cape Mendocino, and along the California Highway 101 corridor to compliment local permanent stations of...
High-resolution seismic data from the Frijoles Fault of the San Gregorio Fault zone, Año Nuevo, California High-resolution seismic data from the Frijoles Fault of the San Gregorio Fault zone, Año Nuevo, California
The U.S. Geological Survey acquired high-resolution P- and S-wave seismic data across the Frijoles Fault strand of the San Gregorio Fault Zone (SGFZ) at Año Nuevo, California in 2012. The SGFZ is a Holocene-active, dominantly right-lateral fault system that trends more than 200 km along the California coastline. The Frijoles Fault is one of several onshore strands of the SGF system, and...

Evaluation of 2-D shear-wave velocity models and VS30at six strong-motion recording stations in southern California using multichannel analysis of surface waves and refraction tomography Evaluation of 2-D shear-wave velocity models and VS30at six strong-motion recording stations in southern California using multichannel analysis of surface waves and refraction tomography
To better understand the potential for amplified ground shaking at sites that house critical infrastructure, the U.S. Geological Survey (USGS) evaluated shear-wave velocities (VS) at six strong-motion recording stations in Southern California Edison facilities in southern California. We calculated VS30 (time-averaged shear-wave velocity in the upper 30 meters [m]), which is a parameter...

Evidence of active Quaternary deformation on the Great Valley fault system near Winters, northern California Evidence of active Quaternary deformation on the Great Valley fault system near Winters, northern California
The Great Valley fault system defines the tectonic boundary between the Coast Ranges and the Central Valley in California, is active throughout the Quaternary, and has been the source of several significant ( M > 6) historic earthquakes, including the 1983 M 6.5 Coalinga earthquake and the 1892 Vacaville–Winters earthquake sequence. However, the locations and geometries of individual...

Nodal seismograph recordings of the 2019 Ridgecrest Earthquake Sequence Nodal seismograph recordings of the 2019 Ridgecrest Earthquake Sequence
The 2019 Ridgecrest, California earthquake sequence included Mw 6.4 and Mw 7.1 earthquakes that occurred on successive days beginning on 4 July 2019. These two largest earthquakes of the sequence occurred on orthogonal faults that ruptured the Earth’s surface. To better evaluate the 3D subsurface fault structure, (P- and S-wave) velocity, 3D and temporal variations in seismicity, and...
