Northern California Must Brace For Major Earthquake in Near Future – US Geological Survey
Four segments of the San Andreas fault system in Northern California are due for an earthquake of magnitude 6.8 or greater, including a section that runs near infrastructure crucial to water supply in much of the state, according to a geological study.
The Green Valley fault northeast of San Francisco between the cities of Napa and Fairfield is poised for a magnitude-7.1 earthquake or stronger, said researchers from the US Geological Survey and San Francisco State University responsible for the report.
The fault is located near dams and aqueducts that supply water from the Sacramento and San Joaquin rivers to the San Francisco Bay area, Southern California, and the farm-heavy Central Valley. The Green Valley fault’s last quake happened “sometime in the 1600s,” AP reported.
The northern Calaveras and Hayward faults in the eastern San Francisco Bay area, as well as the Rodgers Creek fault to the north, are the other segments with enough built-up tension for a magnitude-6.8 or higher quake, the researchers found.
The study, published Monday in the Bulletin of the Seismological Society of America, shows that California “needs to consider more seriously” the major earthquake risks in the region, James Lienkaemper, a US Geological Survey geologist and lead author of the study, told AP.
