EF5s destroy well built homes and sweep their concrete foundations clean of debris. Cars are mangled and tossed hundreds, possibly thousands of meters away. But what exactly does a tornado have to do to earn the most powerful EF5 rating? or an F5 rating? What’s the difference?

In over 20 years of chasing tornadoes I’ve documented at least 8 EF4 tornadoes, but only one EF5. As of the date of this video the last EF5 tornado occurred in Moore Oklahoma on May 20th, 2013. Over 9 years ago. So where have all the EF5’s gone?

BRIEF HISTORY of the FUJITA SCALE (F-scale)
If a strong tornado strikes an instrument that measures wind speeds, The anemometer will likely be blown to smithereens long before it was able to measure and record how fast the strongest winds were. But, If we found the crumbled anemometer a mile away, scientists and engineers can make estimates of what wind velocities might do such a thing.

In 1971 Dr. Ted Fujita developed a method to rate the intensity of tornadoes based on surveys of ground damage. The Fujita Scale has 6 intensity categories from the lightest damage F0 to the incredible F5. With wind estimates from 261-318 mph (419 - 512 km/h), EF5s are powerful enough to throw cars hundreds, possibly thousands of meters and completely sweep away brick homes.

[But the Fujita scale was very limiting with only general descriptions and no account for construction quality. Also, the wind speed estimates
was later deemed by meteorologists and engineers as being too high. For example, a 261 mph wind speed is NOT required to completely destroy a well constructed house and blow away the debris. This damage occurs at significantly lower wind speeds than previously thought.

THE EF SCALE
Revision or enhancement of the Fujita Scale was needed. In 2007 operational use of the ENHANCED Fujita scale began in the United states.
The EF scale has a more accurate estimation of damaging wind speeds.
and has 28 damage indicators all with respective Degrees of damage. The old scale lists an F5 tornado with winds of 261–318 mph (420–512 km/h),
The new scale lists an EF5 with winds above 200 mph (322 km/h),
This is found to be sufficient to cause the damage previously ascribed to the F5 ran
