Or more than all the world's nuclear bombs going off at the
same time but still a lot less than a mile asteroid hit.

Interesting. I wonder how they calculated that.

According to
http://www.seismo.unr.edu/ftp/pub/louie/class/100/magnitude.html
it would have been 32,000 megatons.

I had done a post a while back titled "Energy in a 9.0 quake"
where I stated the following:

A magnitude 9 quake releases an enormous amount of energy.

Referring to the following webpage...
http://staff.imsa.edu/science/geophysics/geosphere/tectonics/eqenergy.html

The 9.0 Indonesian quake released the energy equivilant to
a 32 thousand megaton bomb.

Based on the formula there I did some calculations to try to
put this into perspective. This energy is approximately equal to:

2.13 million Hiroshima bombs.

561 times the largest nuke detonated of 57 megatons.

Equivilant mass/energy conversion (E=mc2) of 24.9 kilograms.
(The largest nuke ever detonated at 57 megatons was 2.7kg)

1000 gigawatts of electricity for the next 72 years.

7.1 billion 100 watt lightbulbs for 100 years.

Total electricity production of US in 2002, for over 161 years.

Total eletricity production of the world in 2001, for over 40 years.

Total energy in sunlight the Earth receives in 4.8 hours.

Amount of energy the Sun produces in 5.8 millionths of a second.

I hope I did all my math right. :)
