Tornado Damage Ratings - Understanding the Enhanced Fujita Scale
If you have an F-2 tornado in the valley of Stoke, NC F5 tornado or a video on the Internet, “F” refers to the Fujita scale (F-scale). The Fujita scale was established in 1971 as a way to obtain an intensity of the tornado is based on the amount of damage to people and structures vegetation. It has been developed by Tetsuya Fujita and Allen in Kansas City, Missouri.
Because many factors wide Fujita was ambiguous and subjective, a new scale was established. The new scale is considered wide Enhanced Fujita Scale or EF and went with effect from 1 February 2007. The scale reflects better Enhanced Fujita tornado damage with regard to wind speed. The EF Scale 28 to repair the damage indicators set up to examine the nature of the vegetation, structures, or were damaged.
Ranking EF-0 tornadoes have wind speeds of 65-85 mph and are known to have caused minor damage often branches and fallen trees. It should be emphasized that, a tornado, which only confirm each damaged is still classified EF-0.
EF-1 Ranking tornadoes have winds of 86-110 km / h are known and have caused damage moderate. It could also be overturned camper and damage to roofs.
EF-2 ranking tornadoes have wind speeds and 111-135 km / h, it is known that extensive damage. A tornado EF-2 is powerful enough to lift a car from the ground and destroying some small structures.
EF-3 ranking tornadoes have winds of 136-165 mph and are known to have caused serious damage. At this level of intensity well built houses are destroyed, and more buildings were extensively damaged.
EF-4-wind speeds, tornadoes of 166-200 km / h and are known to have caused devastating damage. It is at this level as well built houses were completely levelled. The cars may also be removed from the ground and threw long distances.
EF-5 tornadoes have wind speeds exceeding 200 km / h and are known have caused damage incredible. At this level, anything can Districts torn.
Since the Fujita scale improved in the night in the year 2007, there is only one recorded EF-5 tornado. The tornado in Greensburg, Kansas, May 4, 2007. Video Footage of this tornado rarely shows widespread destruction before
