a 7.5 would make a small tsunami, but an 8.2 could make a bad one. They move so fast I guess it would have already hit closer coasts in alaska by now
There are ETA’s of 30 minutes or more from now starting with Kodiak followed by Seward and other locations across the Alaska coast and into British Columbia in the next hour or two.
I was in a 7.5 in Mexico City, 1957, which shook for about 1 1/2 minutes. It was scary and killed close to 200 people, especially in an apartment building that collapsed (after midnight, people in bed). I was walking home from a party although the motion was more like a subway train moving fast rather than a hard shaking. MC is built on mud rather than on rock. When I experienced the Mineral, VA quake, it was a hard shaking for about 15 seconds. The tsunami warning was cancelled. It may have been a sideways slip rather than a drop at the fault line. The terrible tsunami that killed 1/4 million a few years ago was caused by an estimated drop of one side at the fault line of 60 feet along a number of miles. Same situation with the Japan tsunami that damaged the nuclear plant.
