Hurricane Sandy destroyed much of the East Coast of the United States, requiring extensive cleanup efforts. Tornados can reach speeds of 300 mph and be 50 miles long, uprooting trees and destroying large buildings. A tsunami is a series of sea waves caused by underwater earthquakes, landslides, or volcanic eruptions. Tropical cyclones form over oceans near the equator and can have devastating impacts. Heat waves pose health risks like sunburn and blistering from their high temperatures.
