Informational

Event

A magnitude-5.1 offshore earthquake occurred in the Bering Sea near the Alaska Peninsula at around 18:14 Sept. 26. The epicenter was about 37 km (23 miles) south of Sand Point. The tremor occurred at a depth of about 50 km (31 miles), and light shaking was probably felt throughout parts of the southern and central Alaska Peninsula. There have been no initial reports of damage or casualties; 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. 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, particularly near the earthquake's epicenter.

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.
