This report presents the results of a site- specific probabilistic seismic hazard analysis (PSHA) and deterministic seismic hazard analysis (DSHA) for the Near West site in southern Arizona.

We conducted paleoseismic studies in a closed depression along the San Andreas fault on the north flank of Frazier Mountain near Frazier Park, California. We recognized two earthquake ruptures in our trench exposure and interpreted the most recent rupture, event 1, to represent the historical 1857 earthquake.
