Fig. 1: Location of the SAFOD Drilling Site (for a high resolution image please click the map)
The drill site is located on a segment of the San Andreas Fault approximately halfway between Los Angeles and San Francisco. This segment of the San Andreas Fault moves through a combination of aseismic creep and repeating microearthquakes (most recent recurrence was October 20, 2003). It lies at the extreme northern end of the rupture zone of the 1966, Magnitude 6 Parkfield earthquake, the most recent in a series of events that have ruptured the fault five times since 1857. The Parkfield region is the most comprehensively instrumented section of a fault anywhere in the world, and has been the focus of intensive study for the past two decades.
The SAFOD wellhead is located at
| Lat WGS84 | Long WGS84 | Elev (m) (MSL) | Easting m, UTM NAD27 | Northing m, UTM NAD27 |
| 35.9742039 | -120.5521414 | 660.5 | 720807.06 | 3983663.97 |
