where does the san andreas fault go through?
pacific coastal zone
the history of earthquake investigations in california has been largely focused on the san andreas fault system, due to its strong influence in the state as the boundary between the pacific plate and the north american plate; it is the most studied fault on earth. andrew lawson, a geologist from the university of california, berkeley, had named the fault after the san andreas lake (prior to the occurrence of the 1906 san francisco earthquake) and later led an investigation into that event. the san andreas fault ruptured for a length of during the 1906 shock, both to the north of san francisco and to the south in the santa cruz mountains region. several long term forecasts for a large shock along the san andreas fault in that area had been made public prior to 1989 (the event and its aftershocks occurred within a recognized seismic gap) but the earthquake that transpired was not what had been anticipated. the 1989 loma prieta event originated on an undiscovered oblique-slip reverse fault that is located adjacent to the san andreas fault.

section::::observatories.:san andreas fault observatory at depth (safod).









































the san andreas fault observatory at depth (safod) consists of a main borehole that cuts across the active san andreas fault at a depth of approximately 3 km and a pilot hole about 2 km southwest of san andreas fault. data from the instruments installed in the holes, which consist of geophone sensors, data acquisition systems, and gps clocks, as well as samples collected during drilling, will help to better understand the processes that control the behavior of the san andreas fault.
