A magnitude 5.0 earthquake releases the energy of about 200 tons of TNT. Because of the logarithmic increase, a 7.0 quake releases the equivalent of almost 200,000 tons of TNT which is 10 times the strength of the atomic bomb dropped on Hiroshima.

Typically, a number 4 earthquake on the Richter magnatude scale has the same amount of energy as a small atomic bomb, a number 9 earthquake on the Richter scale has the same amount of energy as 199,199,000 tons of dynamite!
