A 6.4 magnitude earthquake rattled Southern California on Thursday and officials said it was the largest to hit the region in 20 years. The quake struck near the city of Ridgecrest, which is located about 160 miles northeast of Los Angeles.
Some injuries were reported in Ridgecrest, authorities said, but the extent is currently unclear. A city in the hospital was evacuated and officials are assessing structural damage to the building.
The United States Geological Survey said the quake struck at 10:33 a.m. PT. The earthquake was initially given a magnitude of 6.6, but was later revised to 6.4. The quake was felt more than 150 miles away in Los Angeles, but no damage was reported.
This was the largest quake to hit Southern California since 1999 and an eerie reminder of the 1994 Northridge quake. The magnitude 6.6 earthquake killed at least 57 people and caused billions of dollars in damage.
