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)[6] 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. On Thursday, scientists released a study warning that the Garlock fault, which runs through the Mojave Desert in southern California, has been moving for the first time on record. "Creep is our friend," he said. © ScienceAlert Pty Ltd. All rights reserved. This article was originally published by Business Insider. Still, Ross said, his team was surprised by their results.

The Garlock Fault, which runs 185 miles from the San Andreas Fault to Death Valley, has not moved much over the past 500 years, the study said. That has happened "several times in the last decade," he added, "and then it just stops creeping at some point.". [2], A study published in October 2019 in the journal Science indicated that a part of the Garlock fault slipped after being triggered by the series of earthquakes in the Ridgecrest area which occurred in July 2019. In fact, the Hollister earthquake occurred near "the creeping section" of the San Andreas Fault, she added. "It's always unusual to have two magnitude-4.5 earthquakes in one week in California," Allen said. After the 2019 events, a very shallow portion of the Garlock slipped slowly, a process known as ‘creep’, perhaps in response to the stress imparted by the Ridgecrest earthquakes, or perhaps due to the ground shaking. The Garlock Fault is believed to have developed to accommodate the strain between the extensional tectonics of the Great Basin crust and the right lateral strike-slip faulting of the Mojave Desert crust.[1]. The Garlock Fault runs from a junction with the San Andreas Fault in the Antelope Valley, eastward to a junction with the Death Valley Fault Zone in the eastern Mojave Desert. The fault has been relatively quiet for the past 500 years, but the strain placed on the Garlock Fault by July's earthquake activity triggered it to start slowly moving, a process call fault creep. The Garlock fault hasn’t ruptured in a … The Garlock Fault moves at a rate of between 2 and 11 mm a year, with an average slip of around 7 millimeters.
