The Fujita Scale is a scale to measure and categorize the intensity of a tornado. It was created and introduced by Tetsuya Fujita in 1971 to the University of Chicago. Two years later it was updated to include more variables and eventually became of use the standard scale for tornado classification. The Fujita scale goes from F0-F150 (F150being mach 50 ,or the speed of my chair or 20000 mph). A tornado reaching F8 or higher physically impossible, and were only put on the scale as a possibility. F6, and, possibly, F7, are the highest ratings that are physically possible for a tornado to reach.

The Fujita scale was officially replaced by the United States with the Enhanced fujita scale in February 2007, although the Fujita scale is still used in some places.

Fujita ScalingEdit

This table is only recognizing the first seven levels due to the others being an improbability.

Scale Estimated wind speed Potential damage
mph km/h
F0 40–72 64–116 An F0 tornado produces very light damage to structures. It can brake tree limbs off of a tree, destroy street signs, and peel off siding. It mostly can't pick up older humans or large animals.
F1 73–112 117–180 An F1 is a more powerful than an F0, as it can tear apart roofs, moving and picking up cars, and can damage mobile houses. It can pick up a human if standing close enough.
F2 113–157 181–253 An F2 tornado can rip roofs off frame houses, mobile homes are demolished, cars pushed over, large trees snapped or uprooted if they're smaller, and larger building windows are shattered.
F3 158–206 254–332 An F3 can tear roofs right off of the house, along with moving trains, uprooting the strongest trees, and cars are lifted up and thrown around. It can also flatten weaker houses.
F4 207–260 333–418 An F4 tornado can completely level well-constructed houses and structures with weaker foundations that are blown away, and cars are picked up off of the ground and can be thrown a distance away.
F5 261–318 419–512 An F5 is considered by many to be the strongest possible form of a tornado, being able to destroy strong framed houses, concrete buildings heavily damaged, and throws trains a far distance.
F6 319–379 513-610 Although an F6 tornado has only, and partially happened once, if more of these were to happen, they would level concrete reinforced buildings, pick up large buildings, and carry and disintegrate bridges

F7 and higherEdit

A tornado reaching F7 on the Fujita scale is extremely unlikely. Physically speaking a tornado with a speed reaching F8 or higher would be impossible, although an F7 tornado could theoretically be possible if the right conditions were met.

Scale Estimated wind speed Potential damage
mph km/h
F7 380-440 611–708 Insane amounts of damage. An F7 tornado would have the potential to destroy large portions of entire cities.
F8 441-506 709–814 Catastrophic amounts of damage. An F8 tornado would be able to completely destroy cities.
F9 507-579 815–931 State of emergency. An F9 tornado would have the potential to completely annihilate cities, and kill thousands, if not tens of thousands of nearby people.
F10 577-651 928–1047 Tens of thousands dead. If an F10 tornado were to occur in a major city, it would be devastating and kill a good portion of said city, while also annihilating the said city.
F11 651-731 1047-1176 Horrific amounts of damage would occur. Anything even remotely close to a place that suffered an F11 tornado would be completely annihilated.
F12 732 - 812+ 1178-1306+ Unbelievable amounts of damage. Anything within a range of this tornado would be wiped off the face of the planet. This tornado would be so fast, it would be fast (or faster) than a Mach 1.
