    La scala Fujita è una misura empirica dell'intensità di un tornado in funzione dei danni inflitti alle strutture costruite dall'uomo. L'origine della scala di misurazione è insolita; l' esplosione atomica di Hiroshima ebbe tra i suoi effetti anche lo sviluppo di numerosi tornado.

  3. The Enhanced Fujita Scale or EF Scale, which became operational on February 1, 2007, is used to assign a tornado a 'rating' based on estimated wind speeds and related damage. When tornado-related damage is surveyed, it is compared to a list of Damage Indicators (DIs) and Degrees of Damage (DoD) which help estimate better the range of wind ...

  4. Unlike the other three scales (Fujita, Enhanced Fujita, and TORRO), the International Fujita scale has overlapping wind speeds within the ratings. The highest tornado rated on the IF scale was the 2021 South Moravia tornado , which was rated an IF4.
