Enhanced Fujita Scale estimated wind speeds: 86 to mph. Typical Observations: Moderate damage. The Fujita Scale. The original Fujita Scale and the new Enhanced Fujita Scale is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man-made structure.

It is quite possible that an even higher percentage of all tornadoes are weak. There is no such thing as an F6 tornado , even though Ted Fujita plotted out F6 -level winds. The Fujita scale, as used for rating tornados , only goes up to F5. By looking at the amount of damage caused to different types of structures, scientists assign the storm an Enhanced Fujita scale classification. From the amount of damage they see, they then try to reverse engineer the storm's wind speeds.

As it tracks along the ground, a tornado's power can change. Can an ef0 tornado kill you? EF0 damage: This house only sustained minor loss of shingles. Even 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.

What type of damage would be expected in a tornado that has a wind speed of mph? The DOD would be a 8, most walls collapsed in bottom floor. Thus, the estimated winds would be - mph with the expected wind speed of mph.

Now, taking this number to the EF-Scale, the damage would be rated EF-3 with winds between - mph. Has there ever been an ef5 tornado? In the United States, between and January 31, there were 50 officially-rated F5 tornadoes, and since February 1, there has been 9 officially-rated EF5 tornadoes.

For each damage indicator, there are 8 degrees of damage DOD ranging from the beginning of visible damage to complete destruction of the damage indicator. The original F Scale did not take these details into account. For example, with the EF Scale, an EF3 tornado will have estimated wind speeds between and mph and kph , whereas with the original F Scale, an F3 tornado has winds estimated between mph kph. The wind speeds necessary to cause "F3" damage are not as high as once thought and this may have led to an overestimation of some tornado wind speeds.
