What is the Fujita Scale of ranking Tornados?
Understanding the Fujita Scale. Dr. T. Theodore Fujita, long one of the world’s foremost tornado experts, developed his namesake scale in the early 1970s. Fujita Scale, or F-Scale, levels correspond to damage typically caused by twister winds of a particular speed. Experts caution that the F-Scale is a useful tool but not a definitive measure, chiefly due to difficulties in precisely judging wind speeds, why a tornado may destroy some structures and leave others untouched, and various other factors. F0 TORNADO (less than 73 mph) An F0, or gale tornado, is more nuisance than menace. Carrying winds as light as 40 mph and topping out at 72 miles per hour, it can break tree branches, damage signs or maybe wrench a brick or two from a chimney. F1 TORNADO (73-112 mph) At the F1 level, a tornado carries hurricane-force winds that can reach 112 mph. It can peel off roofs, push mobile homes off their foundations or blow vehicles off the road. F2 TORNADO (113-157 mph) F2 tornadoes can cause cons
