By the standards of the Enhanced Fujita scale the minimum wind speed for an EF0 tornado is 65 mph. However, simply having a wind at or above this intensity is not enough for there to be a tornado. A tornado is a violently rotating vortex of wind, not just a gust above a certain strength.
There isn't a specific distance because all of the tornadoes in the world are not the same. The typical tornado may travel a mile or so, but path lengths may range from only a few yards to more than 200 miles.
The Waco, Texas tornado traveled 20 miles and was 1/3 of a mile wide.
The tri-state tornado struck many locations along a path 219 miles long. It started near Ellington, Missouri and dissipated near Petersburg, Indiana.ntowns that were hit hard include Annapolis and Leadanna in Missouri, Murphysboro, De Soto, Hurst-Bush, West Frankfort, and Maunie in Illinois, and Griffin, Owensville, and Princeton in Indiana.
Tornadoes can spin at speeds ranging from around 100 to 300 miles per hour, with the strongest tornadoes capable of reaching speeds over 300 mph.
The most recent killer tornado, which occurred in North Carolina on November 16, 2011, killed 2 people. It touched down less than an hour after another tornado in South Carolina that killed 3 people.
F1 winds speeds are 71-112 miles per hour.
An average tornado would probably be in the mid EF1 range with peak winds of 90 to 100 miles per hour. The tornadoes that make national news are usually much stronger.
The 2011 Joplin tornado had peak winds estimated at 225-250 mph (362-402 km/h).
Errr, that would be 70!
Exactly 100 miles
65 miles.
The Joplin tornado traveled 22.1 miles.
at the rate of 30 miles per hour it would take 1 hour. at the rate of 30 miles per hour it would take 1 hour.
At 60 miles an hour, 4. At forty miles an hour, 6.
That would be 5.33 miles per hour.
It depends on how fast the tornado is traveling. The average tornado moves at about 30 mph, so in 15 minutes an average tornado would move 7.5 miles. However, some tornadoes move much faster. The fastest moving tornado on record was found, at times, to travel at 73 mph. At that speed the tornado would travel just over 18 miles in 15 minutes.
The Hallam, Nebraska tornado was 2.5 miles wide and traveled 54 miles.
