A 4.2 magnitude earthquake struck near Lytle Creek, a mountain community east of Los Angeles, on Friday morning, according to the U.S. Geological Survey. The quake was felt across parts of Southern California, including San Bernardino, Riverside, Orange and Los Angeles counties.
The earthquake occurred at 10:55 a.m. local time, about 0.7 miles northwest of Lytle Creek, at a depth of about 7 miles, the USGS said. The epicenter was near the Cucamonga Fault, which runs along the San Gabriel Mountains.
The quake was followed by several smaller aftershocks, ranging from magnitude 0.9 to 2.5, according to the USGS.
Many residents in the area reported feeling the shaking, which lasted for several seconds. Some described it as a jolt, a rumble or a rolling motion.
“It felt like somebody hit the house with a car,” said Lytle Creek resident Mike Horton, who was having breakfast with his wife when the quake hit. “It was just a big boom and then it shook for a little bit.”
“It was pretty scary,” said Lytle Creek resident Jennifer Jones, who was in bed when the quake woke her up. “It felt like the whole house was moving.”
No injuries or major damage were reported from the quake, but some people said they saw cracks in their walls or items falling off shelves.
The Lytle Creek Fire Department said it received several calls from concerned residents, but no emergency responses were needed.
“We did a quick assessment of our area and everything seems to be OK,” said Fire Chief Tim Millhouse.
The earthquake was also felt in nearby cities, such as Fontana, Rancho Cucamonga, Ontario and Pomona.
“It felt like a big truck going by,” said Fontana resident Maria Garcia, who was at home with her family. “We heard a loud noise and then the house started shaking.”
“It was pretty strong,” said Rancho Cucamonga resident David Lopez, who was at work when the quake struck. “It felt like someone pushed my chair.”
The earthquake triggered an alert from the ShakeAlert system, which is designed to provide early warnings of significant quakes in California, Oregon and Washington.
According to the USGS, there is a 2% chance of one or more aftershocks larger than magnitude 4.2 in the next week. The agency also said there is a very low probability of any damage or casualties from the quake.
