COMMUNITY VELOCITY MODEL (CVM) AND OTHER GEOPHYSICAL DATA
The Utah Geological Survey (UGS) and U.S. Geological Survey (USGS) have a cooperative agreement to study earthquake-hazards in Utah with an ultimate goal of producing detailed earthquake-hazards maps, including large-scale ground-shaking maps along the densely populated Wasatch Front urban corridor.
An important component of the ground-shaking maps is developing a three-dimensional model of the subsurface, a Wasatch Front Community Velocity Model (CVM), that incorporates shallow shear-wave velocity (Vs), deep-basin structure, and other effects. To aid in producing these maps, the UGS has compiled databases of Vs and deep-basin geophysical and well logs.
