Huge Earthquakes

In 1811 and 1812, three monstrous earthquakes, probably measuring a full 10 on the Richter scale, struck in America. They did not happen in San Francisco, or even the remote mountains of California, but in the remote hills of the middle latitude, eastern United States – Ohio, Tennessee and Kentucky. The reason few people know of these earthquakes is that none of them caused much destruction to man-made structures, since there were few structures nearby to damage. Is it safer to live in the eastern United States than California? Many scientists say no. Every state in the Union has had earthquakes.
