Mark Zoback and Steve Hickman examine a core from near the actively creeping fault encountered at 10,480 ft (MD) in the SAFOD main hole. Fourteen feet of core were obtained in this run. A second coring run is now being conducted. This core was obtained near one of the fault zones that is slowly deforming the main hole casing. The ''Hawaii"" microearthquake cluster appears to be on this fault, approximately 100m below the depth at which the core was taken. This cluster occurs on a strand of the San Andreas fault that is located along the southwest border of the 250 m-wide ""damage zone"" that hosts multiple active faults.
