On November 30, 2018, at 8:29 AKST (17:29 UTC), a magnitude 7.0 earthquake hit Anchorage, Alaska.[2] The earthquake's epicenter was near Joint Base Elmendorf–Richardson, about 10 miles (16 km) north of the city.

It was followed by a 5.7 aftershock epicentered 2.5 miles (4.0 km) north-northwest of the city.[3][4] There were a total of 40 aftershocks. The earthquake could be felt as far as Fairbanks.[5]

Severe damage to several buildings and a highway overpass near Ted Stevens Anchorage International Airport have been reported.[6] There are no casualties reported so far.[7]

A tsunami warning was issued for nearby coastal areas, including Cook Inlet and the Kenai Peninsula, but they were lifted shortly after.[8]
