A magnitude-6.5 earthquake occurred off the eastern coast of Alaska Peninsula at around 01:10 AKDT Oct. 11. The epicenter was about 114 km (70 miles) east of Chignik. The tremor occurred at a depth of about 46 km (28 miles). Moderate shaking was likely felt across northern parts of the Aleutian Islands and much of Kodiak Island.
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. Aftershocks are likely over the coming days. Authorities have not issued 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.
