Major storms are always dangerous. Superstorm Sandy left 132 Americans dead, damaged and destroyed tens of thousands of homes, left millions without power, and crippled the largest metropolitan area in the United States.

The massive human and economic toll of this disaster came just seven years after Hurricane Katrina. It marked only the latest in a spate of deadly and destructive weather events, including the May 2011 tornado that leveled much of Joplin, Missouri.
