What's ironic is how people expecting a 3 to 9 foot surge, are (happily) surprised when a surge shows up that is only discernible via time-lapse, and
then a freak wave hits a cruise ship at port days later, that measured 26 feet high, killing 2, and injuring many more. Nature... go figure.
It seems like the amount of water that is displaced at the source of the earthquake has a direct effect on the size of the tsunami created. So am I
corrrect in assuming that this quake was more of a lateral slip vs. a vertical thrust. Also, the original video posted by Phage was indeed cool. I
was amazed at the amount of, for lack of a better term "rebound" off of the Aleutians.
The earthquake in Chile occurred in a thrust fault which does produce vertical movement. The generation of a tsunami would depend on the amount of
area lifted as well as the violence and amount of the uplift.
Fortunately neither seem to have been enough to create a destructive Pacific wide tsunami.
