A magnitude 5.0 earthquake struck Sunday night in South Los Angeles, and minutes later a magnitude 3.1 aftershock occurred, according to Caltech.
The "moderate' 5.0 quake struck shortly before 8:40 p.m., a mile east of Lennox, a mile south southeast of Inglewood and 10 miles south southwest of the Los Angeles Civic Center, according to Caltech.
The rumbling lasted about 10 to 15 seconds and was also felt in the valleys and Long Beach. A U.S. Geological Survey Web site indicated it was felt throughout San Diego County as well.
The 3.1 aftershock occurred just after 8:45 p.m. a miles north northwest of Hawthorne and 3 miles southwest of Inglewood, according to Caltech.
The Los Angeles Fire Department went on "earthquake emergency mode," although no damage or injuries were immediately reported, according to police and fire officials.
