The U.S. Geological Survey said the epicenter was about 3.6 miles (6 kilometers) northwest of the Westwood neighborhood, home to the University of California, Los Angeles. Residents near UCLA reported feeling a sharp jolt followed by a short rumble. Some said they were shaken awake in bed.
Former Los Angeles Laker Rick Fox, whose Westwood home was rattled, tweeted that the quake "wasn't funny." Authorities said there were no reports of damage or injuries. "We get these size earthquakes fairly frequently," said USGS seismologist Zachary Reeves to the Los Angeles Times. "Any severe damage would be pretty unlikely."
Earthquake-hardened veterans commented on social media, including some in Hollywood. Actor Josh Gad tweeted that he probably should have checked on his kids, but he scrolled through Twitter instead. Former CBS "Late Late Show" host Craig Ferguson quipped that the rumble had him "sitting up in bed with an automatic weapon waiting for zombies."
The quake was a trending topic on Twitter early Tuesday.
