According to the National Severe Storms Laboratory, the central United States experiences more tornadoes than any other location in the world. Its flat, wide expanse fosters combinations of weather conditions favorable for tornado formation. Texas, Kansas, Nebraska, Oklahoma, Iowa and southern Minnesota are particularly prone to tornadoes.Know More
Tornados are powerful windstorms characterized by a funnel cloud, which is a quickly rotating column of air that stretches from the ground up to a cumulonimbus cloud. Newly formed tornadoes have invisible funnels. As the storm gains speed and power, debris sucked into the tornado give the funnel cloud its characteristic gray color. The whirling column of debris also contributes to the roaring sound associated with large tornadoes.
The National Severe Storms Laboratory reveals that 90 percent of American tornadoes are small, weak and cause little to no property damage. The remaining storms are huge, immensely powerful and cause huge swaths of destruction. These tornadoes topple skyscrapers, toss trucks into the air and present extreme threats to ground-based life.
Although the central United States has the world's highest concentration of tornadoes, the storms occur on every continent except Antarctica. After the contiguous United States and Canada, the areas that experience the most tornadoes are central Asia, South America, South Africa, Australia, New Zealand and Europe.Learn more about Storms

According to NASA, approximately 85 hurricanes occur worldwide each year. Not all of these hurricanes are devastating; some of them appear to be ordinary storms for the most part and only develop into official hurricanes for a few short hours, whereas others can be considered full-force hurricanes for several weeks. In order to be considered an official hurricane, in addition to having an eye with low atmospheric pressure, the circulating wind speeds should exceed 74 miles per hour.Full Answer >
Floods typically occur in lands that are adjacent to rivers or at coastal areas. Land adjacent to rivers, known as floodplains, is susceptible to floods when there is excessive rain. Coastal areas face flooding only when a tsunami or large storm forces the sea to surge inland.Full Answer >
Most tsunamis occur in the Pacific Ocean along the Ring of Fire. Up to 80 percent of tsunamis occur within this geologically active area. Earthquakes and volcanoes are common and cause tectonic shifts that result in tsunamis.Full Answer >
