(RNN) - The United States averages 1,200 tornadoes a year, according to the National Oceanic and Atmospheric Administration. To help classify the strength of those storms, Dr. T. Theodore Fujita created the Fujita Scale in a research paper in 1971. 

In 2007, the National Weather Service revamped the way it categorizes twisters on the Enhanced Fujita Scale. Using information on damage in a given area, the EF Scale estimates wind speeds after a tornado has struck based on 28 indicators.

  • EF0: 65 to 85 mph
  • EF1: 86 to 110 mph
  • EF2: 111 to 135 mph
  • EF3: 136 to 165 mph
  • EF4: 166 to 200 mph
  • EF5: Over 200 mph
