28 de sept. de 2004 · The Town of Parkfield, located on the San Andreas fault in central California, has been the site of an intensive, multidisciplinary earthquake study since the late 1970's. The goal is to observe the fault and surrounding crust at close range at the time before, during and after an earthquake, to better understand the earthquake process and provide a scientific basis for earthquake prediction.
The San Andreas Fault. The presence of the San Andreas fault was brought dramatically to world attention on April 18, 1906, when sudden displacement along the fault produced the great San Francisco earthquake and fire. This earthquake, however, was but one of many that have resulted from episodic displacement along the fault throughout its life ...

10 de mar. de 2014 · The most famous example is California's San Andreas Fault, which stretches some 600 miles (1,000 kilometers) from southern California to north of San Francisco. The sideways motion of the fault's ...
Sesar San Andreas dari atas satelite, dekat Los Angeles. Badan Survei Geologi Amerika Serikat memperkirakan bahwa gempa berkekuatan 6,7 atau lebih besar (yaitu sama dengan atau lebih besar dari gempa bumi Northridge 1994) terjadi sekitar satu kali. Laporan yang sama juga memperkirakan ada kemungkinan 7% bahwa gempa berkekuatan 8,0 atau lebih ...
The San Andreas is the stuff of nightmares because back on April 18, 1906, it caused the most catastrophic event in California history, the great San Francisco earthquake, which was so powerful that it caused a rupture in the land that stretched for 296 miles (477 kilometers). While its magnitude is uncertain, scientists have estimated that it ...
Tectonic Setting. The San Andreas fault in central California. A "creeping" section (green) separates locked stretches north of San Juan Bautista and south of Cholame. The Parkfield section (red) is a transition zone between the creeping and southern locked section. Stippled area marks the surface rupture in the 1857 Fort Tejon earthquake.
