4.5 magnitude earthquake hits San Gabriel Valley, with shaking felt throughout SoCal
ABC7.com staff
An earthquake with a preliminary magnitude of 4.5 rattled Southern California Friday night, hitting near South El Monte with shaking felt in a wide swath of the region.
The USGS says the quake struck less than two miles west-southwest of South El Monte at 11:38 p.m., with a depth of about 10 miles.
Seismologist Dr. Lucy Jones told Eyewitness News the quake was similar in type and location to the deadly 1987 Whittier-Narrows quake which had a magnitude of 5.9. But this one was much smaller in power.
"Here in Pasadena I felt it," Jones said. "It woke me up."
She added that there were at least two aftershocks, measuring 2.1 and 1.6. She also said there is a 5% chance that it was a foreshock to a larger quake.

There is also about a 50% chance of additional small aftershocks within the next 24 hours, she said.
The earthquake was initially estimated at 4.8, then downgraded to 4.6 and then to 4.5.
A shake map produced by the USGS indicates the rattling was felt south to San Diego, north to Santa Barbara and east well out into the Inland Empire and the Mojave Desert, as well as off the coast on Catalina and Santa Cruz islands.
