EarthScope: San Andreas Fault Observatory at Depth (SAFOD) | |
|
Site Characterization (goes to usgs site) |
Goal:
The San Andreas Fault Observatory at Depth (SAFOD) will provide direct
observational data on the composition, physical state and mechanical behavior
of a major active fault zone at depth to test hypotheses pertaining to
faulting and earthquake generation with the ultimate goal leading to earthquake
hazards reduction. more... |

| The drill site is located on a segment of the San Andreas Fault that moves through a combination of aseismic creep and repeating microearthquakes (Figure 1). 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. | ![]() |
