It probably released less destructive energy then did the first conventional firebombing of Tokyo - where the mass of rapidly burning ground level wood buildings (firestorm) added so greatly to the effect of the bombing raid that it shouldn't be judged solely on the number of tons of high explosive that were dropped.
And, repeatedly throughout the entire war, huge weather systems applying much destructive (negative and positive) energy over wide areas showed an ability to stop even the largest invasions known in history literally in their (tank) tracks.
