Early morning 3.1-magnitude earthquake wakes up Los Angeles area

A 3.1-magnitude earthquake shook Southern California near Los Angeles early Monday, Oct. 3, the U.S. Geological Survey reports.

The 2-mile deep quake hit 3 miles east of Yorba Linda at 1:24 a.m., according to the USGS.

About 575 people from as far away as Long Beach and Thousand Oaks reported feeling the tremor to the agency. There were no reports of damage or injury.

“Earthquake… anyone else feel it in OC?” one person asked on Twitter.

“That earthquake felt like it was right under my damn bed,” reported another Twitter post.

Magnitude measures the energy released at the source of the earthquake, the U.S. Geological Survey says. It replaces the old Richter scale.

Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech. Quakes below 2.5 magnitude are seldom felt by most people.

Yorba Linda is a city of 68,000 about 40 miles southeast of Los Angeles.
