View of the San Andreas Fault in Parkfield, CA. The town of Parkfield, located on the San Andreas Fault in central California, is one of the worlds most seismically active areas. It has been the site of an intensive earthquake study since the late 1970's and a team of scientists recently reached the faults active zone through a 2-mile deep borehole. This project, named SAFOD, is a major step in learning more about earthquakes and maybe predicting them.
