A sheriff's official from the county's Pico Rivera station told ABC7 news there were no reports of injuries or damage. Likewise, Los Angeles Fire Department spokesman Erik Scott reported via email alert, “No significant injuries reported.” The department went off “earthquake alert” about 5:13 a.m., he reported. However, a possible earthquake-caused sinkhole along the southbound 5 freeway at Paramount Boulevard in Downey opened up, ABC7 reported. The California Highway Patrol issued a Sigalert for the freeway, with two right lanes closed early Tuesday
The temblor struck at a depth of about 11 miles, the USGS indicates. The quake appears to have struck on the Whittier fault: Map and data. Southern Californians living as far south as San Diego reported feeling the shaker to the USGS.
Caltech seismologist Kate Hutton told ABC7 there's about a five percent chance that a quake of such magnitude could be a precursor to a larger temblor.
More than 10,000 people and counting reported their experiences with the quake on the USGS' “Did You Feel It” site. On Twitter, “Earthquake” and “Pico Rivera” were in the top five trending topics early Tuesday.
A 5.9 shaker, called the Whittier Narrows earthquake, hit along the same fault on Oct. 1, 1987, reportedly killing three. That epicenter was beneath Rosemead in the San Gabriel Valley.
