A magnitude-4.1 earthquake occurred in northern California at around 09:29 Oct. 18. The epicenter was about 4 km (2.5 miles) south-southwest of Isleton and 52 km (32 miles) south-southwest of Sacramento. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt across northern and central California. There have been no initial reports of damage or casualties.

Advice

Plan accordingly for aftershocks. Consider vacating multistory buildings if operating in affected areas until authorities confirm their structural integrity. Allow additional time for air and road travel, as aftershocks may prompt brief disruptions. Seek updated information on road conditions before driving in hilly areas in the affected region due to potential landslides.
