added by magmatism from below and sedimentation from above. The seismic survey will image
the effects of rapid sedimentation upon extension and magmatism during continental rifting. The
vertical and lateral partitioning of strain will be investigated in this oblique rift. The southernmost
San Andreas Fault is considered at high risk of producing a large damaging earthquake, yet
structure of the fault and adjacent basins are not currently well constrained. The seismic survey
will image the structure of the San Andreas and Imperial Faults, structure of sedimentary basins in
the Salton Trough, and three-dimensional seismic velocity of the crust and uppermost mantle.
Fieldwork is tentatively scheduled for January 2010. The purpose of this poster and a workshop to
be held immediately after the 2008 SCEC meeting is to communicate plans for the seismic project
and encourage synergy with piggyback and complementary studies.
