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.
This table is only recognizing the first seven levels due to the others being an improbability.
|Scale||Estimated wind speed||Potential damage|
|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.
