An additional four tornadoes which occurred prior to 1950, all in Europe, have been officially rated F5 or equivalent by the Because the distinctions between F4/EF4 and F5/EF5 tornadoes are often ambiguous, the official ratings of numerous other tornadoes formally rated below F5/EF5 or equivalent have been disputed, with certain government sources or independent studies contradicting the official record. These wind speeds can top 200 miles per hour and cause utter devastation. So a tornado shelter can pay off, especially if you live in a vulnerable high-wind zone area.

Ultimately, a new scale was devised that took into account 28 different damage indicators; this became known as the In the United States, between 1950 and January 31, 2007, a total of 50 tornadoes were officially rated F5, and since February 1, 2007, a total of nine tornadoes have been officially rated EF5.Several other tornadoes have also been documented as possibly attaining this status, though they are not officially rated as such. Apartment buildings will show little signs of damage from EF-0 tornadoes.EF-1 tornadoes produce wind speeds between 86 and 110 miles per hour.
