An earthquake in Southern California has shaken millions of people awake and put emergency services on full alert.

The quake, a magnitude-4.4, had its epicenter around 10 miles east of downtown Los Angeles and struck just after 4am local time, according to the U.S Geological Survey.

There have been no reports of injuries, damage or power outages, though the California Highway Patrol did report a ten-foot stretch of buckled concrete on Interstate 5, they could not immediately say whether the damage was caused by the quake.

Emergency services in California have said they’ve received calls from a few alarmed residents, but not as many as they’d expected.
Following the devastating earthquake in Haiti on Jan. 12, and the violent earthquake in Chile, Californian residents have grown increasingly concerned that a similar calamity might effect them.

Authorities, however, have called for calm, saying that there is a small chance Tuesday’s tremor is a sign of a larger event, but that the chances are small and that as time passes, the chances diminish even more.
