US: A magnitude-4.2 earthquake occurs in Lytle Creek, San Bernardino County, California at around 10:55 Jan. 5

A magnitude-4.2 earthquake occurred in San Bernardino County, California, at around 10:55 Jan. 5. The epicenter was about 1 km (0.6 miles) west-northwest of Lytle Creek. The tremor occurred at a depth of about 9 km (5.5 miles), and light shaking was probably felt throughout parts of central and southern California, US, and northern Baja Calif., Mexico. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light aftershocks are likely over the coming days.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
