A 4.2-magnitude earthquake struck near the Lytle Creek area of San Bernardino County on Friday, Jan. 5, and was felt throughout Southern California.
The earthquake happened at 10:55 a.m. The San Bernardino County Fire Department said on social media that there were no immediate reports of damage or calls for service.
The U.S. Geological Survey shake map showed reports came in from Oxnard, Palm Desert and San Diego, among other areas. Lytle Creek is near the Cajon Pass by the 15 Freeway in San Bernardino County. Other nearby cities are Rancho Cucamonga, Fontana, Devore, Hesperia and Mt. Baldy.
An earthquake of this magnitude usually will cause no more than minor damage.
