From Wiki 5A
(Redirected from Fujita scale (F-scale))
This is the fujita scale:
- EF0
- EF1
- EF2
- EF3
- EF4
- EF5
- A EF0 tornado does the least amount of damage. Light damage. Some damage to chimneys; shallow-rooted trees pushed completely over; branches broken off some trees; sign boards damaged.
- A EF1 tornado the wind speeds range around 73-112 mhp. The damage is moderate. Trees broken and fallen; house trailers tipped over; roofing shingles peeled off roofs and large road signs blown to the ground.
- A EF2 tornado has winds around 113 to 157. Damage is considerable. Roofs can be torn from frames of weaker houses; Barns and other out door builds are ripped down; cars can be blown off the highway; Danger of flying debris
- A EF3 tornado can have winds in this ballpark 158-206 mph. This damage is severe. Flying debris are everywhere; Walls of houses are blown to the ground: houses get moved off their firm foundation; windows of skyscrapers are broken; cars are lifted up off the ground; closets may give shelter.
- A EF4 is pretty bad winds are around 207-260. Damage is devastating. Less than 25 of these tornadoes happen every year. Whole houses are leveled; cars are blown very far; skyscrapers get twisted; the debris are so bad that wood gets driven into metal; little shelter above ground
- A EF5 is the worst tornado. Luckily only one or two happen a year but on April 3 of 1974 six EF5 tornadoes happen. Winds are around 261-318. Damage is so bad that it is classified as incredible. House are just debris all that is left is the foundation; cars and trucks are moved a half a mile; steel structures are almost destroyed. Tornadoes are very dangerous storms we need the fujita scale.
