Descr: Old industry seismic reflection data from the Tucson Basin in southeast Arizona image a low-angle normal fault (the Santa Rita fault) that crops out along the trend of late Quaternary fault scarps cause by large-magnitude (M ~6.7-7.6) earthquakes. Velocity independent dip analysis from shot records of the Santa Rita Fault indicates that it has a true dip of ~20 to a depth of 6 km. This project is designed to acquire medium and high-resolution seismic images of the Santa Rita Fault up to the surface.
