Event

The US Tsunami Warning Center canceled its previously issued tsunami warning for Alaska's Cook Inlet and Kenai Peninsula at 09:58 (local time) on Friday, November 30. The warning was issued following a 7.0-magnitude earthquake that struck 13 km (8 mi) north of Anchorage at 08:29. A total of nine additional aftershocks, with magnitudes up to 5.7, were recorded as of 09:00. Further aftershocks are likely in the coming hours and days.

Anchorage police reported major infrastructure damage across the city, including to homes and buildings. Several roads and bridges are closed due to damage, including the Seward Highway (AK-1) which is closed near McHugh Creek due to a rockslide. Following a suspension of all flights, Ted Stevens Anchorage International Airport (ANC) reopened around 10:00 though residual delays may persist. Airport authorities also reported significant damage to the airport road and urged extreme caution.

Advice

Individuals in the affected areas are advised to monitor the situation, prepare for aftershocks, anticipate road damage and transportation disruptions, and adhere to instructions issued by local authorities.

During an earthquake, individuals are advised to protect themselves as much as possible from falling debris if indoors (e.g. under a table), to move away from windows and exterior walls, and do not attempt to leave the building unless there is an immediate danger. If outdoors, move away from any tall structures, such as buildings, utility wires, and streetlights.
