Red Orbit: Study shows San Fransisco area faults may be connected, raises possibility of massive earthquake
A new seismic study has found that two San Francisco faults may be connected, raising the possibility of a highly-destructive, massive earthquake.
The study looked at the Hayward Fault, which ruptured in a devastating 19th century Bay Area quake, and the Rodgers Creek Fault, which sits beneath San Pablo Bay. The possibility of the two being connected would pose the threat of a far more powerful quake in the future, a new seismic study has found.
US Geological Survey researcher Janet Watt conducted the study underwater using an acoustic instrument.
