NASA images show earth’s movement in Easter quake

The magnitude-7.2 earthquake that struck near Calexico on Easter Sunday shifted the Earth’s crust in the area about 31 inches downward and to the south, according to radar images and data collected by researchers at NASA’s Jet Propulsion Laboratory.

Airborne radar images of the area taken by the JPL-developed Uninhabited Aerial Vehicle Synthetic Aperture Radar were posted online by NASA for the first time Wednesday.

Researchers used data collected by the airborne radar to detect changes in the distance between the aircraft and the ground over repeated GPS-guided flights. According to JPL, they combined data from flights on Oct. 21 and April 13 to determine the deformities in the Earth’s crust.

The UAVSAR has been mapping the San Andreas and other faults from north of San Francisco to the Mexican border every six months since spring 2009, looking for ground motion and increased strain along faults, according to NASA.

“The goal of the ongoing study is to understand the relative hazard of the San Andreas and other faults to its west like the Elsinore and San Jacinto faults, and capture ground displacements from larger quakes,” said JPL geophysicist Andrea Donnellan.

  • Rancho Santa Fe Invasive Plants and Better Alternatives
    By Steve Jacobs, Nature Designs In California we are lucky to live in a mild climate that allows us to grow amazing landscapes. Because of this mild climate, plants from other parts of the world often thrive; and some grow so well they become known as invasive. These plants ‘jump fences’ and ‘throw seeds.’ Their […]
  • Rancho Santa Fe School District’s robotics program receives new funding
    The Rancho Santa Fe School District is making its school’s robotics program more robust this year, allocating $42,500 in stipends to staff coaches just like the district does for its athletics program. “I think the program has taken a big step,” said Superintendent Lindy Delaney. “I think we’re on our way toward developing a great program there.” John Galipa […]
