San Francisco Bay Area 3-D Velocity Model
Entry ID: USGS_BAVM

[ Update this Record ]

Summary
Abstract: Overview of the 3-D Velocity Model

The USGS is developing a 3-D seismic velocity model for the San Francisco Bay
Area primarily for the calculation of realistic strong-ground-motion synthetic
seismograms for local earthquakes. The model, gridded at 100-m intervals,
extends from the ground surface to the Moho, from the coast to the Great
Valley, and from the Geysers (38.8°) to Watsonville (36.9° ... View entire text
