What percentage of tornadoes are F4 or F5?
Tornadoes that are intense enough to warrant an F4/EF4 or F5/EF5 rating are classified as “violent.” Fortunately, these tornadoes are extremely rare, accounting for only about two percent of all tornadoes.
What is a F1 F2 F3 and F5 tornado?
F1 – F1 tornadoes are moderate. The wind speeds are between 73 mph and 112 mph. They can overturn mobile homes and push cars off the road. F2 – F2 tornadoes are significant with wind speeds between 113 mph and 157 mph. F5 – F5 tornadoes are incredibly strong with wind speeds between 261 mph and 318 mph.
What are the 5 levels of a tornado?
Tornado Classification
| Weak | EF0, EF1 | Wind speeds of 65 to 110 mph |
|---|---|---|
| Strong | EF2, EF3 | Wind speeds of 111 to 165 mph |
| Violent | EF4, EF5 | Wind speeds of 166 to 200 mph or more |

How wide is a F4 tornado?
An EF5 tornado, the highest number on the “Enhanced Fujita Scale of Tornado Intensity,” is any tornado that has wind speeds of 200 mph or higher. The tornado, which carved a path 16.2 miles long near El Reno, Okla., surpasses a 2.5-mile-wide F4 tornado that hit Hallam, Neb., in 2004.

What percentage of tornadoes are F2?
From 1970 to 2002, F2 tornados account for 19% of all tornados occurence in the United States. From 1950 to 2011, F2 and F3 tornados account for 29% of all tornados related deaths in the United States. A tornado rated an F2 has winds speeds between 113 to 157 MPH (181 to 253 km/h).
What is the wind speed of a F1 tornado?

What damage can a F3 tornado cause?
Any F3 tornado can cause severe damage to the property and vegetation. They can tear off walls and roofs, flip over cars, overturn trains, and so on. The winds generated by these tornadoes go at speeds between 158 and 206 miles per hour, while the diameter of F3 tornadoes is somewhere in the range of 176–566 yards.
What is an example of a F4 tornado?
This includes for example breaking down houses and lifting cars up in the air. Due to being so powerful, F4 tornadoes can leave a significant death toll behind. The wind speeds of these tornadoes are in the range of 207–260 miles per hour, while their diameter is between 0.3–0.9 miles large. F5 Tornado
