That is VERY misleading. I guarantee you that a 9.0 does not feel 32,000 times more powerful than a 6.0 and it also doesn't do 32,000 times the damage....NOT EVEN CLOSE!
No...it isn't. For those of that didn't fail grade school math, earthquake magnitudes work off of a 10-base log scale. So the energy (you are thinking amplitude) of earthquakes to each successive magnitude releases ~32x more energy. 6.0 to a 9.0 is three orders of magnitude so 32 * 32 * 32 is 32,768. I guarantee you, if you go read a book or two, this will make sense.

Put down your books and experience a decent sized earthquake. If a 9.0 was 32,000 times a 6.0 there would be nothing left on this planet.
