Southern California residents were jolted awake by a 3.8 magnitude earthquake that struck near Ontario late Thursday night. The quake, which occurred at 11:38 p.m., was felt as far as Los Angeles and Orange Counties, according to the U.S. Geological Survey (USGS).
The epicenter of the quake was located about two miles east-southeast of Ontario, near the Ontario International Airport, at a depth of about eight miles. No injuries or damages were reported, but some people took to social media to share their experiences.
Ontario quake came just a week after a 4.6 magnitude quake centered in Malibu rocked the region, with strong shaking felt over a wide swath of Southern California. That quake, which occurred on Feb. 8, was the largest to hit the area since a 5.1 quake in La Habra in 2014.
Earthquakes are common in Southern California, which lies along the Pacific Ring of Fire, a zone of seismic activity that encircles the Pacific Ocean. The USGS estimates that there is a 31% chance of a 7.5 or larger quake occurring in the next 30 years in the region.
