F4 and F5 are the two strongest categories of tornado on the Fujita Scale.
The Fujita scale rates tornadoes from F0 to F5 by the severity of damage done.
An F4 tornado will level most houses and strip the bark from trees.
An F5 tornado, with winds than can exceed 300 mph, will completely annihilate a well built house and sweep it clean off its foundation. Cars and even houses can be thrown hundreds of feet.
It a sequence of numbers beginning with 0 and 1 where each number is the sum of the two preceeding numbers. F1 = 0 F2 = 1 F3 = F2 + F1 = 1 + 0 = 1 F4 = F3 + F2 = 1 + 1 = 2 F5 = F4 + F3 = 2 + 1 = 3 F6 = F5 + F4 = 3 + 2 = 5 etc.
esc, f1, f2, f3, f4, f5, f6, f7, f8, f9 :)

If you mean other countries, then yes.Tornadoes have been recorded on every continent except Antarctica. Countries besides the U.S. that have a high incidence of tornadoes include Canada, Australia, Bangladesh, Argentina, and South Africa.
PRESS ALT AND F4 AT THE SAME TIME
A little more than 1% of tornadoes are rated F4 and F5 with F5 tornadoes being less than 0.1%
Oklahoma has had the most F4 and F5 tornadoes. Though it is tied with Texas, Iowa, and Alabama in terms of F5 tornadoes in the past 60 years.
About 1.1% of tornadoes are rated F4, and less than .1% are rated F5.
Yes. There have been documented cases of F5 tornadoes and some F4 tornadoes tearing asphalt from roads.
No. There has never been an F5 tornado recorded in Colorado. It has had a handful of F4 tornadoes.
Most violent tornadoes (F4 and F5) occur in the months of March-June.
Although Florida has a very high concentration of tornadoes, they generally are not as strong or as destructive as the ones that occur in Tornado Alley. For example, since official records began in 1950 Florida has had 2 F4 tornadoes and no F5 tornadoes. By comparison Oklahoma has had 57 F4 tornadoes and 6 F5 tornadoes.
Yes. Large F4 and F5 tornadoes have been known to destroy entire towns.
There have been there have been 112 known F5 or EF5 tornadoes based on records since 1880. However, the number in older records is likely higher. It is very difficult to tell the difference between F4 and F5 tornadoes based on old records, and in the case of uncertainty an F4 rating is given.
F4 and F5 are the two highest levels on the Fujita scale, which rates tornadoes on a scale of F0 to F5 based on the severity of the damage they cause. These two levels fall into the broad category of "violent" tornadoes. Typical F4 tornado damage includes well-built houses leveled and trees debarked. Typical F5 damage consists of well-built houses wiped clean off their foundations, and heavy damage to reinforced concrete structures.
F4 and F5 are the two strongest categories of tornado on the Fujita scale. A damage based scale which rates tornadoes from F0 to F5. An F4 tornado will reduce most houses to piles of rubble. An F5 tornado will completely annihilate almost any house and wipe it clean off its foundation. Winds in an F5 can exceed 300 mph.
No. F4 and F5 tornadoes account for less than 1% of all recorded tornadoes. About 90% of tornadoes are rated F0 or F1.
