US: Magnitude-4.7 offshore earthquake occurs near northeastern California at around 08:26 Sept. 30
Magnitude-4.7 earthquake occurs in northeastern California, US, at around 08:26 Sept. 30. No immediate reports of damage or injuries.
Event
A magnitude-4.7 earthquake occurred in northeast California at around 08:26 Sept. 30. The epicenter was about 3 km (2 miles) south-southwest of Ferndale, Calif. The tremor occurred at a depth of about 16 km (10 miles), and light-to-moderate shaking may have been felt near Eurokea and areas close to the epicenter, and weak-to-light shaking was probably felt as far as southeastern Oregon. There have been no initial reports of damage or casualties as a result of the earthquake; significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are likely over the coming days. The event has not prompted any tsunami advisories.
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 where shaking occurred.
Advice
Out of an abundance of caution, consider vacating multistory buildings where shaking occurred until authorities confirm their structural integrity. Monitor and plan for aftershocks.
