The EF Scale is the standard way to measure tornadoes based on wind damage.
The original Fujita Scale (or F Scale) was developed by Dr. Theodore Fujita. All tornadoes, and other severe local windstorms, were assigned a number according to the most intense damage caused by the storm.
| Wind Speed | Wind Damage | |
|---|---|---|
| F0 | 40-72 mph (64-116 km/h) | Light Damage |
| F1 | 73-112 mph (117-180 km/h) | Moderate Damage |
| F2 | 113-157 mpg (181-253 km/h) | Considerable Damage |
| F3 | 158-207 mph (254-332 km/h) | Severe Damage |
| F4 | 208-260 mph (333-419 km/h) | Devastating Damage |
| F5 | 261-318 mph (420-512 km/h) | Incredible Damage |
The enhanced F Scale (EF Scale) was implemented in the United States on February 1, 2007. The EF scale uses three-second wind gust estimates based on a more detailed system for assessing damage, taking into account different building materials.
