If and when an earthquake is going to happen is a crapshoot. Any time, any place, any strength.

Chile had the world's worst recorded earthquake, 9.5, on May 22, 1960. The recent one was 'only' 8.8.

Alaska had a 9.2 quake in 1964, with surface land displacements of as much as 38 feet. Think of that when people talk about earthquake-proof buildings. (Sneering? ME????)

The only thing you can do is be prepared for disasters in general. Be ready to leave, or ready to stay and camp in your backyard.
