Technical Service Center

Geophysics and Seismotectonics Group (86-68330)

Jerry Wright, Manager

We provide specialized geological, geomorphological, seismological, and geophysical expertise for site-specific and regional earthquake and geomorphology studies, Quaternary geology, and engineering geophysics.

Information and services that we provide include:

Natural hazards for risk analysis through probabilistic earthquake hazard studies
Numerical and statistical analysis and modeling, including software for flood-frequency analysis, two- and three-dimensional flow modeling, ground motion synthesis, and seismic tomography
Earthquake loadings, including site-specific ground motions and response spectra
Probabilistic risk analyses for dam safety and design evaluations
Seismic monitoring of Reclamation facilities for real-time structural response information for post-earthquake assessment and emergency notification
Paleoseismic investigations to define earthquake hazards
Geomorphology, geomorphological processes, and Quaternary history for stream evaluation and restoration, site characterization, environmental impact, and other investigations
Complete geophysical site characterization services including data acquisition, processing, analysis, and integration with borehole and other geologic and hydrologic information
Surface, borehole, cross-hole, and surface-to-borehole geophysical surveys to determine a wide range of subsurface physical properties and conditions, including centimeter-level global positioning system surveys in support of scientific and engineering investigations

We directly operate regional seismic networks in the Western United States and maintain an extensive network of digital and analog strong-motion recorders.
