Geophysics & Seismology

Geophysics and Seismology

RIZZO conducts various geophysical tests at project sites in support of site response analysis, including surface surveys and downhole loggings.

RIZZO performs high-resolution seismic surveys to evaluate shallow subsurface geology, as well as to delineate and verify possible Quaternary faulting.
