Question: is ridgecrest on the garlock fault?
Answer: The 2019 Ridgecrest quakes stressed the Garlock Fault. If it ruptured in a large shock, it would likely trigger a San Andreas earthquake north of Los Angeles. The greater Los Angeles area lies near the San Andreas Fault. The 2019 magnitude-6.4 and magnitude-7.1 Ridgecrest earthquakes were largely unforeseen.
