On 18 March 1925 a tornado travelled at least 352 km through the US states of Missouri, Illinois and Indiana. It killed 695 people, more than any other tornado in US history. The tornado lasted 3.5 hours, longer than any other in recorded history.
Has there ever been an F6 tornado?
In reality, there is no such thing as an F6 tornado. When Dr. Fujita developed the F scale, he created a scale that ranges from F0 to F12, with estimated F12 winds up to mach 1 (the speed of sound).
How big can a tornado get?
The average twister is about 660 feet wide and moves about 30 miles an hour. Most don’t travel more than six miles before dying out. Massive tornadoes, however—the ones capable of widespread destruction and many deaths—can roar along as fast as 300 miles an hour.
What is the slowest tornado ever?
An F0 tornado is the weakest tornado on the retired Fujita Scale. An F0 will have wind speeds less than 73 mph (116 km/h).
Has anyone ever been picked up by a tornado and survived?
Yes, many people have survived being sucked up by a tornado by great luck, or by the grace of God. In fact, I’ve been directly struck by two tornadoes and survived both with little injury! Unfortunately most often though, people are killed. It’s a very violent event.
What does the F mean in a tornado?
Incredible. The Fujita (F) Scale was originally developed by Dr. Tetsuya Theodore Fujita to estimate tornado wind speeds based on damage left behind by a tornado. An Enhanced Fujita (EF) Scale, developed by a forum of nationally renowned meteorologists and wind engineers, makes improvements to the original F scale.
Can u hear a tornado coming?
As the tornado is coming down, you should hear a loud, persistent roar. It is going to sound a lot like a freight train moving past your building. If there are not any train tracks near you, then you need to take action.

What are the 5 levels of a tornado?
More information on the Fujita and Enhanced Fujita Tornado Rating System. Even though 80% of Wisconsin’s tornadoes have been rated weak in intensity, Wisconsin has experienced 3 tornadoes with winds speeds in excess of 260 mph since 1950.
