San Diego, California, officials: ‘Not a good sign’ on new quake-threat alerts

SAN DIEGO, California — Officials in San Diego County, California announced Wednesday that they have issued a major earthquake threat alert for the city.

Officials said the earthquake is within a magnitude 5.6 earthquake range, with an epicenter about 25 miles southeast of San Diego.

The alert covers a swath of San Jose, Santa Clara, Los Angeles and Ventura counties, and a portion of San Francisco, the county said in a statement.

“San Diego County is prepared to respond to an earthquake that threatens the entire county, but that response will require additional resources and may not be possible immediately,” the statement said.

A more detailed statement will be posted at 11:00 a.m.

Thursday on the county’s official website.

It was the second earthquake to hit the San Diego area since Tuesday.

On Tuesday, a magnitude-5.7 quake shook the coastal city of San Pedro, about 10 miles northeast of the city, killing two people and injuring dozens more.

Last week, an 8.1-magnitude quake shook a town in the San Fernando Valley, destroying homes, sending mudslides and knocking out power to about 100,000 people in a region already experiencing the strongest El Niño weather in decades.

Since then, at least six more quakes have been recorded in the region.
