LOS ANGELES (Tribune News Service) A major California fault capable of producing a magnitude 8 earthquake has begun moving for the first time on record, a result of this years Ridgecrest earthquake sequence destabilizing nearby faults, Caltech scientists say in a new study released in the journal Science on Thursday.
In the modern historical record, the 160-mile-long Garlock fault on the northern edge of the Mojave Desert has never been observed to produce either a strong earthquake or even to creep the slow movement between earthquakes that causes a visible scar on the ground surface. But new satellite radar images now show that the fault has started to move, causing a bulging of land that can be viewed from space.
This is surprising, because weve never seen the Garlock fault do anything. Here, all of a sudden, it changed its behavior, said the lead author of the study, Zachary Ross, assistant professor of geophysics at Caltech. We dont know what it means.
