What is the smallest tornado ever?
The tornado that Peggy Willenberg and Melanie Metz filmed on the highway in front of them in Minnesota a couple of years ago had to be no more than two to three feet in diameter (at least the visible condensation funnel) in its initial stage. Ah, the “Twister Sisters” !
What is the minimum speed of a tornado?
Original Fujita Scale estimated wind speeds: less than 73 mph. Enhanced Fujita Scale estimated wind speeds: 65 to 85 mph.
Can an EF0 tornado kill you?
Though well-built structures are typically unscathed by EF0 tornadoes, falling trees and tree branches can injure and kill people, even inside a sturdy structure. … EF1 damage: Cause major damage to mobile homes and automobiles, and can cause minor structural damage to well-constructed homes.
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).
What happens if two tornadoes collide?
When two tornadoes meet, they merge into a single tornado. It is a rare event. When it does occur, it usually involves a satellite tornado being absorbed by a parent tornado, or a merger of two successive members of a tornado family.

How fast do tornadoes travel? Tornadoes generally travel form the southwest and at an average speed of 30 miles per hour. However, some tornadoes have very erratic paths, with speeds approaching 70 mph.
What happens if you throw a bomb in a tornado?
By changing heat flow and wind movements through the detonation of a powerful explosion in the path of a tornado, it could be possible to disrupt the energy of the twister and eliminate the threat. … The heavy-handed nature of using a massive explosion to stop a tornado is therefore possible, but not practical.
Is the inside of a tornado calm?
There is mounting evidence, including Doppler on Wheels mobile radar images and eyewitness accounts, that most tornadoes have a clear, calm center with extremely low pressure, akin to the eye of tropical cyclones.
Can an F1 tornado pick up a person?
Yes, a tornado can lift a person but not that high. Consider this: a human body is roughly 300 times denser than the air. As it is being lifted, it suffers the spinning moment of the tornado; mostly counter-clockwise in the northern hemisphere but, sometimes clockwise (anticyclonic tornado).
What are 5 warning signs that a tornado may occur?

- A dark, often greenish, sky.
- Wall clouds or an approaching cloud of debris.
- Large hail often in the absence of rain.
- Before a tornado strikes, the wind may die down and the air may become very still.
- A loud roar similar to a freight train may be heard.
- An approaching cloud of debris, even if a funnel is not visible.
