Parkfield, the self-proclaimed earthquake capital of the world, was the location of a Magnitude 6 earthquake at 10:15am today. The epicenter was 15 miles south of the drill site on the San Andreas fault at a depth of 7.9 km. The drill site was subjected to fairly intense shaking but nobody was hurt and no significant damage was sustained. Scientists are thrilled to have witnessed ""the Big One"" and we anticipate a wealth of data associated with this event.
