Objectives: Determine an accurate two-dimensional velocity structure across the vicinity of San Francisco, from an accretionary prism overlying continental crust to normal oceanic crust. Image the lower crust and moho beneath the marginal sedimentary pile that is invisible in available multichannel seismic reflection lines across the margin. Establish the extent of subducted oceanic crust under the margin. Determine an accurate two-dimensional velocity structure along the San Francisco Bay. Search for major faults crossing the bay and continental margin. Augment the BASIX data set of marine multichannel seismic reflection and land seismic refraction to help determine whether major faults in the Bay Area are connected at depth.
