A major Southern California fault line that could produce an 8.0 magnitude earthquake began to move for the first time in 500 years, according to a study published in the journal Science on Thursday.
Geophysicists from the California Institute of Technology and NASA’s Jet Propulsion Laboratory found the Garlock Fault is beginning a process called fault creep and has slipped 0.8 inches since July, The Associated Press reported. The fault runs east to west between Death Valley and the San Andreas Fault.
