Updated at 4:26 p.m. ET: A small earthquake rattled Southern California on Sunday morning, causing buildings to shake in downtown Los Angeles. There were no immediate reports of damage or injury.
The quake had a preliminary magnitude of 3.9 magnitude and struck at 8:24 a.m., the U.S. Geological Survey said. It was centered about 5 miles east-southeast of Santa Clarita, and about 24 miles north-northwest of downtown Los Angeles.
It may not have been a hurricane, but an earthquake and tsunami warning worried state agencies along the West Coast. NBC's Miguel Almaguer reports.
Shaking was felt across the Santa Clarita Valley, in downtown Los Angeles, in West Hollywood and along LA County beaches, The Associated Press reported.
The quake was followed by several smaller aftershocks.
A sheriff's dispatcher in Santa Clarita told the AP there were no calls reporting damage or injury.
