Earthquake Faults Around San Francisco Are Dangerously Interconnected
Geologists have discovered that two deadly faults beneath San Francisco—the Hayward and Rodgers Creek faults—may be linked. Should one slip, it could trigger the other fault to collapse as well, causing an earthquake even larger than the one that struck back in 1989.
Geologists are very familiar with the Hayward Fault and its potential to unleash devastation along the populated subdivisions just east of San Francisco, but a new paper published in Science Advances by researchers from the US Geological Survey shows that a less-appreciated neighbor to the north, the Rodgers Creek Fault, may be connected. The discovery of a “missing link” between the two faults could change the way city officials plan for the next big earthquake in the Bay area. – READ MORE
