What is List of F5 and EF5 tornadoes?
This is a list of tornadoes rated F5 on the [[Fujita scale]], EF5 on the [[Enhanced Fujita scale]], IF5 on the {{ill|International Fujita scale|en}}, or T10-T11 on the [[TORRO scale]], which is equivalent to an F5 rating. These ratings (F5/EF5/IF5/T10/T11) are the highest possible ratings on the various global tornado intensity scales. These various scales attempt to estimate the strength of a tornado by classifying the damage caused to nature and man-made structures in the tornado's path.{{refn|group=note|The [[Fujita scale]] was devised under the aegis of scientist [[Ted Fujita|T. Theodore Fujita]] in the early 1970s. Prior to the advent of the scale in 1971, tornadoes in the United States were officially unrated.<ref>Multiple sources: *{{harvnb|Grazulis|1993|p=141}} *{{harvnb|Grazulis|2001a|p=[https://archive.org/details/tornadonaturesul0000graz/page/131 131]}} </ref> The Fujita scale has been superseded by the [[Enhanced Fujita scale]] in the U.S. since February&nbsp;1, 2007;<ref>{{cite web |last1=Edwards |first1=Roger |title=Enhanced F Scale for Tornado Damage |url=http://www.spc.noaa.gov/faq/tornado/ef-scale.html |website=The Online Tornado FAQ |publisher=Storm Prediction Center |access-date=February 25, 2016 |date=March 5, 2015}}</ref> Canada used the old scale until April&nbsp;1, 2013;<ref>{{cite web |title=Enhanced Fujita Scale (EF-Scale) |url=https://www.ec.gc.ca/meteo-weather/default.asp?lang=En&n=41E875DA-1 |website=Environment and Climate Change Canada |access-date=February 25, 2016 |archive-url=https://web.archive.org/web/20160303220706/http://www.ec.gc.ca/meteo-weather/default.asp?lang=En&n=41E875DA-1 |archive-date=March 3, 2016 |date=June 6, 2013 }}</ref> nations elsewhere, like the United Kingdom, apply other classifications such as the [[TORRO scale]].<ref>{{cite web|title=The International Tornado Intensity Scale |url=http://www.torro.org.uk/tscale.php |website=Tornado and Storm Research Organisation |year=2016 |access-date=February 25, 2016 |archive-url=https://web.archive.org/web/201603051203
