Surface rupture at Parkfield

The geologists have been combing the ground along the San Andreas fault in Parkfield, California, after the 28 September earthquake. The California Geological Survey has a page with current results, including photos of road cracks and such. There was some surface rupture, none of it greater than 5 centimeters. And see lots more data and photos at Ramón Arrowsmith's Parkfield page at Arizona State University.
