List of F4, EF4, and IF4 tornadoes
(Redirected from Draft:List of F4 and EF4 tornadoes)
 |
This is a list of tornadoes which have been officially or unofficially labeled as F4, EF4, IF4, or an equivalent rating. These scales – the Fujita scale, the Enhanced Fujita scale, the International Fujita scale, and the TORRO tornado intensity scale – attempt to estimate the intensity of a tornado by classifying the damage caused to natural features and man-made structures in the tornado's path.
Tornadoes are among the most violent known meteorological phenomena. Each year, more than 2,000 tornadoes are recorded worldwide, with the vast majority occurring in North America and Europe.[1][2] In order to assess the intensity of these events, meteorologist Ted Fujita devised a method to estimate maximum wind speeds within tornadic storms based on the damage caused; this became known as the Fujita scale. The scale ranks tornadoes from F0 to F5, with F0 being the least intense and F5 being the most intense. F4 tornadoes were estimated to have had maximum winds between 207 mph (333 km/h) and 260 mph (420 km/h).[3][a]
Following two particularly devastating tornadoes in 1997 and 1999, engineers questioned the reliability of the Fujita scale. Ultimately, a new scale was devised that took into account 28 different damage indicators; this became known as the Enhanced Fujita scale.[4] With building design and structural integrity taken more into account, winds in an EF4 tornado were estimated to between 166 mph (267 km/h) and 200 mph (320 km/h).[5] The Enhanced Fujita scale is used predominantly in North America. Most of Europe, on the other hand, uses the TORRO tornado intensity scale (or T-Scale), which ranks tornado intensity between T0 and T11; F4/EF4 tornadoes are approximately equivalent to T8 to T9 on the T-Scale. Tornadoes rated IF4 on the International Fujita scale are also included on this list.
List of F4/EF4 tornadoes
[edit]The most recent EF4 tornado occurred on May 21, 2024, which impacted the town of Greenfield, Iowa during the tornado outbreak sequence of May 19–27, 2024.
Pre-1950
[edit]The National Weather Service in the United States did not rate any tornadoes prior to 1950. Other organizations like the European Severe Storms Laboratory (ESSL) and Environment and Climate Change Canada (ECCC) on the other hand, did rate tornadoes prior to 1950. The only violent tornado that impacted the United States prior to 1950 and has an official rating is the 1946 Windsor–Tecumseh tornado, which received a rating from ECCC. However, the impact to the United States remains officially unrated.

| October 23 | 1091 | UK | Greater London | London | 2 | London tornado of 1091 — A violent tornado destroyed 600 houses, damaged the Church of St Mary-le-bow, and killed two people. While this tornado did not receive a rating on a tornado intensity scale, a publication in the Journal of Meteorology by M. W. Roe described the tornado as a “violent whirlwind”, so it is believed to have been equivalent to an F4 tornado.[6][7] | M. W. Roe |
| September 11 | 1535 | Poland | Lower Silesian | Oleśnica | 5 | An F4 tornado that destroyed part of the town. The written account of this tornado was done by Dr. Alfred Wegener, which is in the CLIMDAT archive located at Leipzig University.[8][9] | ESSL |
| July 15 | 1582 | Germany | Thuringia | Rockhausen | 0 | This F4 tornado nearly destroyed a village, leaving only two houses that remained untouched. This may have been twin tornadoes instead of just one tornado.[8][10] | ESSL |
| July 1 | 1625 | Russia | Tver Oblast | Toropets | 0 | This violent F4 tornado caused a 125 kilometres (78 mi) path of destruction, reaching a maximum width of 2,500 metres (2,700 yd). Numerous houses and churches were obliterated and numerous trees were snapped or uprooted.[8] | ESSL |
| October 23 | 1666 | UK | Lincolnshire | 4 Villages in Lincolnshire | 3 Fatalities | A high end F4/low end F5 past through Welbourn, Wellingore, Navenby and Boothby Graffoe in Lincolnshire. Killing 3 people. Rated T8/9 by TORRO which is equivalent to F4 on the Fujita scale. Slight possibility of being an F5.[11] | TORRO |
| May 22 | 1872 | Estonia | Historic country of Livonia | Unknown | 7 (14 injuries) | 74 farms were damaged and a church was destroyed.[8] | Heino Tooming, ESSL[b] |
| September 6 | 1882 | Denmark | Silkeborg Municipality | Gødvad | 0 | The tornado destroyed an entire barn, "crushed" six strong oak half-timbered homes, destroyed turf homes, scoured an oat field, and picked up the water in a pond. "A stone house had all of its wooden roof tiles ripped off and the planks reportedly broken like glass". "Deep ground scouring" occurred in numerous places as well.[8] | ESSL |
| July 1 | 1891 | Germany | North Rhineland | Lind, Süchteln, Anrath, Krefeld | 3 (100 injuries) | This short-lived, extremely fast-moving F4/T9 tornado destroyed the towns of Lind, Süchteln, Anrath, and Krefeld. According to the European Severe Storms Laboratory, this tornado had a path of 20 km (12.43 mi) and only was on the ground for 4 minutes, meaning the forward moving speed of this tornado was about 300.00 kilometres per hour (186.41 mph). Hail up to 8 cm (3.15 in) occurred with this tornado.[12] | ESSL |
| September 21 | 1897 | Italy | Apulia | Oria | 55 | Houses and stone-walled buildings collapsed. The tornado's maximum width was 850 metres (930 yd) and had a path length of 36 kilometres (22 mi).[8] | ESSL |
| July 17 | 1902 | Canada | Ontario | Chesterville, Winchester | Several | The tornado was 50–60 rods (250–300 m; 820–990 ft) wide and tore dwellings and outbuildings into pieces.[13][14][15] | ECCC |
| June 29 | 1904 | Russia | Moscow Oblast | Moscow | 9–200 (≥93 injuries) | 1904 Moscow tornado — [8] | ESSL |
| June 30 | 1912 | Canada | Saskatchewan | Regina | 28 (300 injuries) | Regina Cyclone – An F4 tornado that completely leveled several structures and caused others to explode as the pressure inside the structures rose when the tornado passed overhead. The tornado caused a 12 kilometres (7.5 mi) path of destruction and had an approximate width of 150 metres (490 ft).[16][17] With 28 deaths, it remains Canada's deadliest tornado. | ECCC |
| November 24 | 1928 | Denmark | Southern Denmark | Hostrup, Esbjerg, Alslev | 0 | An F4 tornado that impacted Southern Denmark along a path of 4.6 kilometres (2.9 mi). Several barns were destroyed near Hostrup and gables on homes were destroyed. A home’s walls were cracked in this area as well. A pump that was “deep into the ground” was ripped up and thrown 10 metres (11 yd). In the area of the pump, a “literal” two-story brick farmhouse was “erased to the ground”, which suggested F4 level intensity.[8] | ESSL, DMI |
| July 20 | 1931 | Poland | Lublin | Lublin | 6 | This tornado is officially rated F4; however, the Polish Weather Service estimated winds at 246 to 324 mph (396 to 521 km/h), potentially ranking it as an F5. Numerous structures were "razed to the ground".[8] | ESSL |
| July 11 | 1934 | Finland | Eastern Finland Province | Kiuruvesi | 0 | An F4 tornado was observed which crossed over land and water.[8][18] | ESSL, FMI, NWS[c] |
| December 26 | 1940 | Cuba | Mayabeque Province | Bejucal | 20 (100+ injuries) | The F4 tornado collapsed numerous houses and other structures. The tornado had an estimated width of 400 metres (440 yd) and an estimated windspeed of 350 kilometres per hour (220 mph).[19] | INSMET |
| June 17 | 1946 | United States, Canada |
Michigan, Ontario |
River Rouge, Windsor, LaSalle, Tecumseh | 17 | 1946 Windsor–Tecumseh tornado – Officially rated F4; however, one home had a portion of its concrete block foundation swept away, indicating borderline F5 damage. The tornado knocked out power to most of Tecumseh as well. This tornado is not officially rated by the National Weather Service (NWS) in the United States as NWS did not begin to rate tornadoes until 1950, so the damage done in the United States remains unrated.[20][21] | ECCC |

[edit]Possible F4/EF4 tornadoes with no official rating or lower rating
[edit]Because the distinctions between tornadoes ratings are often ambiguous, the official ratings of numerous other tornadoes formally rated below F4/EF4/IF4 or equivalent have been disputed, with certain government sources or independent studies contradicting the official record. This list includes tornadoes rated F4/EF4/IF4 or equivalent by government meteorologists, non-government tornado experts (i.e. Thomas P. Grazulis or Ted Fujita) or meteorological research institutions (i.e. European Severe Storms Laboratory) that rated a tornado differently than the official government organization in charge of the rating. Published academic papers or presentations at academically held meteorological conferences that rate tornadoes as F4/EF4/IF4 or present some evidence to support damage or winds in that category are also ways a tornado can be added to this list.
1870s
[edit]Tornado expert Thomas P. Grazulis gave F4 ratings to 48 tornadoes that occurred in the United States in the 1870s.

| August 7 | 1950 | Germany | Rhineland-Palatinate | Andernach | 0 | Swirling utility poles marked the devastating path of the natural event. Heavy trunks had been swirled hundreds of meters away. Considerable damage occurred on a chicken farm and the beets were torn out of a field, meaning it was "probably F3 or F4 tornado?" | ESSL |
| June 8 | 1951 | United States | Oklahoma | Corn | 0 | This is event is officially documented as a single F3 tornado, but photographs showed that there were actually two slow-moving tornadoes from one storm.

This tornado was the first in the United States to be caught on film and was also one of the most photographed tornadoes in Oklahoma at the time. Grazulis rated the second tornado, which destroyed several barns before dissipating west of Corn, F2 and noted that it may have been anticyclonic. | Grazulis |
| June 27 | 1951 | United States | Illinois | Heman | 0 | Tornado outbreak sequence of June 25–27, 1951 – The tornado is officially rated F3. Grazulis also rated the tornado F3, but noted that it caused "probable F4 damage." Two entire farms were "wiped out" near Heman. | Grazulis |

Numerous outbuildings were destroyed, farm equipment was damaged, and power poles and trees were downed. It was initially rated EF4 based on DOW wind measurements showing that tornado had winds in the EF4-EF5 range, but was downgraded since none of the damage indicators were over EF3. However, it was acknowledged that the tornado was likely at least EF4 intensity at some point in its life. | NCEI |
| May 16 | 2015 | United States | Texas, Oklahoma | Hardeman, Wilbarger (Texas), Jackson (Oklahoma), Tillman, Kiowa | 0 | Multiple-vortex wedge tornado. Metal buildings, outbuildings, and trees sustained major damage or were destroyed. Power poles were broken and a few homes were damaged as well.
