A magnitude 7.0 earthquake shook Anchorage, Alaska and the surrounding area on Friday morning. The shaking also triggered a wave of tsunami warnings along the Alaska coast with more likely around the Pacific. As of 9:59am AKST (December 1, 5:59am AEDT), the tsunami warning has been cancelled for Alaska.
The strongest of a series of quakes struck just after 8:30am AKST (December 1, 4:30am AEDT) about 13km north of Anchorage.
Numerous strong aftershocks continue to jolt the region, with Alaska's Earthquake Center tweeting that 'many more' are expected. In the immediate aftermath, reports on social media indicated there are power outages, collapsed overpasses, fires, and sinkholes, though as with all disasters, it's worth waiting to hear more official information.
The earthquake also triggered a tsunami warning for Cook Inlet and the Southern Kenai Peninsula. "For other US and Canadian Pacific coasts in North America, the level of tsunami danger is being evaluated," the US Tsunami Warning System said in a bulletin.
The warning has caused widespread gridlock as Alaskans fled the coast while navigating roads that have reportedly been damaged by the shaking.

Alaska is no stranger to earthquakes, with its southeastern coastline sitting on the edge of the Pacific and North American tectonic plates. The state recorded the strongest earthquake in North American history in 1964.
That magnitude 9.2 earthquake caused widespread damage and unleashed tsunami waves across the Pacific, including one that reached an astounding 60m in height as it funnelled. This quake wasn't nearly as strong so any tsunami is unlikely to reach that level, but this is still a dangerous situation and should be monitored closely if you live anywhere across the Pacific.

This is what happened on the 6th floor of the Nesbett Courthouse during the Anchorage #earthquake. Both attorneys jumped under their desks. Evacuated the building after the shaking stopped. pic.twitter.com/dqHGPCv6XO
