- seismic Pre-stack Depth Migration (Bauer et al., 2013)
- We derived direct images of sub-vertical fault structures of the San Andreas fault system in the northern Salton Trough (Southern California). The SAF is imaged along Line 4, through the Mecca Hills, as a number of steeply dipping fault segments that collectively form a flower structure, above 5 km depth, that sole into a moderately NE-dipping fault below that depth.
