Most powerful earthquakes
Each increase of 1 point on the Richter scale represents an increase of x 10 in the disturbance and a release of 30 times more energy. The smallest measurable events release energy in the order of 20J (equivalent to dropping a brick from a table top) - the most powerful recorded earthquake released energy equivalent to the simultaneous detonation of 50 of the most powerful nuclear bombs!

It was off the coast of Chile in 1960. I believe a 9.3 on the scale.
The next 2 were the "Good Friday" Alaska quake of 1964, and the Indian Ocean quake that triggered the tsunami in 2004. They estimated both of those to be about 9.1 to 9.2.
