> The 7.2 Mexicali earthquake was so powerful that it shifted the Earth's
> crust up to 10 feet in Mexico, according to radar images and data released
> Wednesday by NASA.
>
> The Easter Sunday quake also shifted the crust 31 inches near Calexico.
The
> data for the California shift came from NASA satellites and those for the
> Mexican shift from European and Japanese satellites. Both sets of data
were
> analyzed by NASA's Jet Propulsion Laboratory.
>
> Eric Fielding, a JPL geophysicist, said shifts would be obvious in some
> places because the earth cracked. But the shifts generally occurred in
> remote desert and agricultural areas, so it's unclear whether people
noticed
> the altered landscapes there.
>
> The shifts are large, particularly for California, but they are not
> record-setting. The largest such "deformation" ever measured was 60 feet
> after the massive 9.5 earthquake that struck Chile in 1960, Fielding said.
> Along the coastline, places that used to be at sea level jutted up to 30
> feet above the lapping water, he said.
>
> The temblor, the largest to hit the Southern California/Baja California
> region in years, also increased the likelihood of earthquakes on faults
> north of the Mexican border, including the San Jacinto and Elsinore
faults,
> said Andrea Donnellan, a JPL geophysicist.
>
> However, she said it's too early to know which faults are more likely to
> rupture.
>
> "This, combined with future measurements, will tell us how the region is
> changing and how" future earthquakes will behave, Donnellan said. "All
these
> faults to the north had more stress added to them. We want to know which
are
> more likely to break."
>
> She added that the large Mexican quake probably reduced the chance of a
> temblor along some of the faults on the American side, though she said the
> focus right now is on which pose a greater danger.
>
> The Elsinore fault runs through portions of San Diego County, including
near
> Julian, Temecula and Lake Elsinore, according to the Southern California
> Earthquake Data Center. The San Jacinto fault runs near such cities as
> Hemet, Loma Linda and San Bernardino.
>
> The Easter quake killed two people and collapsed numerous buildings in the
> Mexicali area. There was more than $90 million in damage in California
> alone, mostly in Imperial County.
>
> The images used to measure the shift in crust were taken by the
Uninhabited
> Aerial Vehicle Synthetic Aperture Radar, which is operated by JPL.
