This Alaskan earthquake was one of the largest to ever happen at 9.2 on the Richter scale!

Wouldn't it be magnificent if you could knock on your door and a person on the other side of the world could hear it in their home? In order for this to happen you would have to hit the door pretty hard. In fact, your strike would have to equal the measure of force put out by around 950 megatons of TNT. Not many people can do that.

What can make this sort of impact? The Anchorage earthquake of 1964. Hitting the richter scale at around a 9.2, equivalent to 4.0 exajoules, one of the largest measurements of earthquake related energy to ever have existed on earth. A very strong punch would measure somewhere in the ballpark of 156 joules. That is 1 quindecillionth of a hexajoule. You would have to work on your swing for a very long time.

Lasting over 4 minutes, the Anchorage earthquake caused tsunamis and tremors in a massive radius including over 20 countries. Motion directly related to the earthquake was reported all over the earth. An estimated 15 people were killed immediately by the earthquake and another 129 were killed by the subsequent disasters.
