Intellectual Merit The high-resolution seismic refleciton data we collected extend the record of blind-thrust-related folding tfrom the deep pretroleum-industry seismic relcfection data to within 20 m of the surface. These high-res data provide us with specific targets fro drilling of boreholes and cpts to define the recent folding history of these large blind thrust faults. In addition, the data that we have collected, together with industry provided seismic survey data, will help define the earthquake potential (location, magnitude, and recurrence) of the Western San Cayetano and Ventura blind-thrust faults so that these sources can be included in regional seismic hazards assessments. As part of the Harvard-led companion project, these high-resolution data have been used to help develop new fault representations for the SCEC CFM.
Broader Impacts These new data provide evidence for recent, discrete zones of folding above two large blind thrust fault ramps - the Ventura and western San Cayetano faults - that may link together to generate very large-magnitude earthquake beneath the central and western transverse ranges. these new high-resolution data also provide the target needed for precise dating of recent folding events that we can use to better to define the frequency and displacements in such events (2011 work).

On the educational front, this project constitutes a part of USC graduate student Lee McAuliffe's Ph. D. research.
