the Garlock fault slipped after being triggered by the series of earthquakes in the Ridgecrest area which occurred in July 2019. Reports in the Los Angeles Times indicated that a magnitude 8 earthquake along the Garlock fault would have the potential for grave disaster. The last significant ruptures on the Garlock were thought to be in the years 1050 AD and 1500 AD. Research has pinned the interval between significant ruptures on the Garlock as being anywhere between 200 and 3,000 years, depending on the segment of the fault. The most recent notable event in the Garlock Fault Zone was a magnitude 5.7 near the town of Mojave on July 11, 1992. It is thought to have been triggered by the Landers earthquake, just two weeks earlier. However, no surface slippage of the fault itself had been recorded in modern times until 2019. Following a series of earthquakes on nearby minor faults in late July 2019, the Garlock Fault was observed moving about 2 cm (0.8 in) between July and October accompanied by numerous minor earthquakes, a state known as fault creep, and producing a bulge in land observed by satellite radar images.
