3.4 magnitude earthquake shakes East County

Quake centered south-southeast of Borrego Springs

JULIAN, Calif. - An earthquake with a magnitude of 3.4 shook the East County on Sunday, according to the U.S. Geological Survey.

"We feel them out here all the time, but not like this one," said Cheryl Gillott, a state parks worker in Ocotillo Wells. "It was pretty big."

The 9:04 a.m. temblor was centered about 16 miles east-southeast of Julian, or 17 miles south-southeast of Borrego Springs, according to the USGS. That spot would be in the isolated desert mountains about 51 miles east-northeast of downtown San Diego.

People scattered around East County reported feeling shaking from the quake, which was centered at a depth of about 3 miles below the surface. It was also reportedly felt in the cities of San Diego and Riverside.

Gillott, an employee at the Ocotillo Wells State Vehicular Recreation Area Discovery Center, described the quake as having a rolling, as opposed to jolting, motion.


Automated seismographs and computers originally calculated the quake to be magnitude 3.3, but the data was reviewed by seismologists and the magnitude was changed to 3.4.
