The 160-mile Garlock fault in California has begun moving for the first time on record and is now at a higher risk of rupture, local geophysicists say.
The fault is the second-longest in California, stretching from the edge of Ventura County in the west to the southern border of Death Valley National Park in the eastern part of the state. It’s capable of producing an 8.0 magnitude earthquake, according to a recent study.
