A Tsunami warning is in effect following a large 7.8 magnitude earthquake struck Alaska.

The quake struck at 11:12 p.m. Tuesday night 98 km SSE of Perryville, according to United States Geological Survey.

A tsunami warning was initially issued for south Alaska and the Alaska Peninsula, but was cancelled shortly afterwards.

The level of tsunami danger for British Columbia is still being evaluated.

UPDATE: At 12:31 a.m. Wednesday, Emergency Info BC announced there is no tsunami threat to BC.

Moments after the earthquake in Alaska, Earthquakes Canada reported a 4.6 earthquake in the Port Hardy area, however, it was later retracted as a false alert based on an automatic detection due to the Alaska earthquake.

The USGS upgraded the quake from a preliminary magnitude 7.4 to a 7.8.
