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 we've 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 don't know what it means."
