A magnitude-5.1 earthquake centered near Los Angeles caused no major damage but filled the region with aftershocks throughout the night, the Los Angeles Times reported.
The U.S. Geological Survey said the quake struck at about 9:09 p.m. Friday and was centered near Brea in Orange County, about 20 miles southeast of downtown Los Angeles, at a depth of about 5 miles, according to the LA Times.
Vin Scully was calling the Freeway Series at Dodger Stadium on Friday night when the 5.1 quake began during the sixth inning, according to the LA Times.
"A little tremor in the ballpark, I am not sure if the folks felt it, but we certainly felt it here," Scully said, the LA Times reported. "A tremor and only that thank goodness."
The epicenter was only about 2 to 3 miles underneath the surface, which "means the shaking is very concentrated in a small area," Caltech seismologist Egill Hauksson said, the LA Times reported. He added it was similar to the Puente Hills thrust fault, which caused the Whittier Narrows earthquake back in 1987.
Hauksson said the earthquake sequence was unusual in that the 5.1 quake was preceded about an hour earlier, at 8:03 p.m., by a weaker foreshock of 3.6, according to the LA Times.
Brea police said there were some minor injuries during a rockslide in Carbon Canyon, which caused a car to overturn and the Carbon Canyon Road to be closed, police said, the LA Times reported.
More than two dozen aftershocks ranging from magnitudes 2 to 3.6 were recorded, according to the USGS, the LA Times reported. Earlier in the evening, two foreshocks registering at a magnitude-3.6 and magnitude-2.1 hit nearby in the city of La Habra.
Public safety officials said crews were inspecting bridges, dams, rail tracks and other infrastructure systems for signs of damage, according to the LA Times.
At Disneyland, some rides were shut down as a precaution, according to guests there, the LA Times reported. Los Angeles officials said they had no reports of damage in the city.
Friday's quake hit a week after a pre-dawn magnitude-4.4 quake centered in the San Fernando Valley rattled a swath of Southern California, the LA Times reported. That jolt shook buildings and rattled nerves, but did not cause significant damage.
Southern California has not experienced a devastating earthquake since the 1994 magnitude-6.7 Northridge quake killed several dozen people and caused $25 billion in damage, according to the LA Times.
