According to the United States Geological Survey, the earthquake struck at 11:12 p.m. PDT 105 kilometres south southeast of Perryville, Alaska with a depth of 28 kilometres.
There were many reports of the earthquake being felt in Alaska and there continue to be aftershocks in the same area.
There were tsunami warnings and advisories for parts of coastal Alaska after the earthquake, prompting sirens and evacuations, but as of 1:23 a.m PDT, all tsunami warnings and advisories were cancelled.
According to the National Tsunami Warning Center in Palmer, Alaska, the maximum tsunami height (the highest recorded water level above the tide level as of 1:04 a.m.) was 0.8 ft (0.2 m) at Sand Point, Alaska.
Therefore a tsunami did occur after the earthquake but no longer poses a threat. Some areas may continue to see small sea-level changes.
The #homer spit is being evacuated. There’s been a massive #earthquake to the south and the tsunami sirens are blaring. Cars are streaming up Skyline, one after the other outside my window. #Alaska pic.twitter.com/KOQFcabnhH
