Crap
a magnitude 5.0 earthquake is about 200 tons of TNT, magnitude 6.0 is 6,270 tons, 7.0 is 199,000 tons, 8.0 is 6,270,000 tons, and 9.0 is 99,000,000 tons of TNT. As you can imagine, 99 million tons of TNT is enough to destroy just about anything, and is the equivalent of about 25,000 nuclear bombs
