The Jet Propulsion Laboratory's UAVSAR project scans California's faults from 45,000 feet up
Southern Californians may be living on borrowed time. At least two sections of the notorious San Andreas Fault, a hotbed of tectonic tension, are apparently overdue for a huge earthquake that could devastate Los Angeles County or San Francisco. Though they can neither prevent nor pinpoint it, scientists would like to get as much information as they can as to where and when the next "Big One" could happen. Increasingly, they're turning to air and space to learn what's happening 10 miles underground.
A new radar plane developed at NASA's Jet Propulsion Laboratory is the first American system designed to map earthquake hot zones.
