In response to "I think that huge one in Alaska in the 50s 60s? Was over 10 minutes. Crazy!! That 7.2 I was in was over a minute and a minute seemed like 5 + minu -- nm" by Bacon

This says the 9.2 Alaska quake 1964 was 4 minutes long. Not sure where I remember 10 minutes

Unless it was farther out where the energy goes down but the time goes up as the waves get further apart.
