Howcome VOlcanoes don't destroy more stuff? I've noticed that volcanoes can be tens of thousands of times more powerful than the nuke on Hiroshima ,take Mt.St.Helens. Helens was close to 27,000 times more powerful that that bomb dropped but didn't do nearly as much damage. A 20 megaton nuke can be felt up to 40 miles away but from the looks of it The Mt.St.Eruption didn't go out more than 3 miles or so. With that kind of power I'd expect a huge crate about 7 miles from center to edge. But all that happen was the trees in the surrounded forest got leveled, the wildlife burned and around 60 people died. I know not alot of people were not around the immediate vacinity but that's not alot of casualties. With many many thousands of megatons in kinetic power I'd think that the person whom took those pictures while it was erupting would have just fried to death. I don't know that it was a person now but a camera shouldn't stand that force. And then there's Mt.Penatubo......Mt.St.Helens big grandpa..........could knock a whole island off the map.
