Highlights
SAFOD is located in central California within the transition between the creeping and locked sections of the San Andreas Fault, 9 km NW of Parkfield, Ca li f . a n d j u s t N W o f t h e r u p t u r e zone of the 2004 M6.0 Parkfield earthquake

Summary
SAF 83o depth (Boness and Zoback, 2006). In addition, heat flow measurements in the SAFOD pilot hole and main hole (to 3.1 km depth) are consistent with shallower data in the region which show no evidence of frictionally-generated heat (Williams et al, 2004; 2006).
