List of F4, EF4, and IF4 tornadoes explained

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 207mph and 260mph.[3]

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 166mph and 200mph.[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

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

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 231091UKGreater LondonLondon2London 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

1882DenmarkSilkeborg MunicipalityGødvad 0The 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.
1891GermanyNorth RhinelandLind, Süchteln, Anrath, Krefeld3 (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 202NaN2 and only was on the ground for 4 minutes, meaning the forward moving speed of this tornado was about 300km/h. Hail up to 82NaN2 occurred with this tornado.[11]

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 10m (30feet). In the area of the pump, a “literal” two-story brick farmhouse was “erased to the ground”, which suggested F4 level intensity.ESSL, DMI

Possible F4/EF4 tornadoes with no official rating or lower rating

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

Tornado expert Thomas P. Grazulis gave F4 ratings to 48 tornadoes that occurred in the United States in the 1870s.

Possible F4/EF4 tornadoes with no official rating or different rating
DayYearCountrySubdivisionLocationFatalitiesNotesRated by
1950GermanyRhineland-PalatinateAndernach0Swirling 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
1951United StatesOklahomaCorn0This is event is officially documented as a single F3 tornado, but photographs showed that there were actually two slow-moving tornadoes from one storm. Grazulis rated the larger one that hit Corn F4. It destroyed 25 homes and 22 farm buildings, damaged 80 additional homes and buildings, and killed 26 heads of hogs and cattle and 1,650 chickens. Objects picked up by the tornado was carried as far as 90miles away. Ample warning prior to the storm striking the towns resulted in no casualties from this tornado. 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
1951United StatesIllinoisHeman0Tornado 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
1953United StatesIndianaNewtown3The tornado is officially listed as a long-tracked F3 tornado, but it is listed by Grazulis as family of four tornadoes, the second of which he rated F4 based on the damage done north of Newtown.Grazulis
1953United StatesIndianaFairview3The tornado is officially listed as a long-tracked F3 tornado, but it is listed by Grazulis as family of four tornadoes, the fourth of which he rated F4 based on the damage done near Fairview. Official records do not bring the tornado into Randolph County, where the damage reportedly took place.Grazulis
1953United StatesNebraskaHebron51953 Waco tornado outbreak – The tornado is officially listed as an F3 and Grazulis also rated it F3. However, he noted that F4 damage may have occurred outside of Hebron where two of 13 homes were described as "leveled." The top of Hebron High School was also torn off.Grazulis
1953United StatesWisconsinAmery41953 Waco tornado outbreak – This is officially listed as a long-tracked F2 tornado, but was more likely a family of tornadoes according to Grazulis, who rated the tornado F4 based on a swath of severe damage from east of New Richmond to near Amery. In all, 113 homes were damaged or destroyed and 215 other structures were affected by this tornado according to reports from local staff of the American Red Cross, although damage outside of the most severe damage in Amery was in sparsely populated areas and not well documented.Grazulis
1954United StatesMissouri, IowaSiam (IA)0Official records list the storm as an F2 tornado, but it was rated F4 by Grazulis. At least two farm homes were leveled and swept away. The track of the tornado is incorrectly listed in the NCEI as only being in Taylor County, Iowa.Grazulis
1957United StatesMinnesotaGlyndon, Riverton0Tornado outbreak sequence of June 20–23, 1957 – Three farms were destroyed with near-F5 damage to one home. Officially, this storm is listed as part of the track of the F5 tornado that hit Fargo, North Dakota, but a study by Fujita found the track to be a five-member tornado family, of which the Fargo tornado was the third and this one was the fourth.Fujita, Grazulis
United StatesSouth Dakotanear MartinProduced possible F5 damage over farmland north of Martin according to Grazulis, who rated the tornado as an F4. A church "disappeared" and one home "seemed to evaporate into the air." This tornado is listed as only F3 in the official database.Grazulis
United StatesVirginianear South Boston (injuries)A six-room farmhouse was leveled, its debris strewn for acres. This tornado is listed as only F3 in the official database, but was rated F4 by Grazulis.Grazulis
JapanChiba PrefectureMobara (injuries)[24] A house was lifted off its foundation and disintegrated, and steel rods at a construction site were bent down to the ground. Video analysis indicated wind speeds of 930NaN0 at 120m (390feet) above ground level.[25] Fujita's analysis would make this the first record of an F4 tornado in Japan.[26] Fujita
Jan 182007GermanyBrandenburgLauchhammer0 (1 injury)A long-tracked tornado which was officially rated high-end F3/T7 hit multiple villages in eastern Germany. Four buildings were levelled completely in Kahla, and surveyors noted possible T8 damage in some locations, which equals F4 damage.ESSL
United StatesKansasnear BenningtonTornado outbreak of May 26–31, 2013 – A large, very slow-moving, and erratic wedge tornado remained over mostly farm lands. 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
United StatesTexas, OklahomaHardeman, Wilbarger (Texas), Jackson (Oklahoma), Tillman, KiowaMultiple-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. According to the National Centers for Environmental Information, video and radar evidence suggest that this was likely a violent (EF4 or stronger) tornado over a sparsely populated area.[27] NCEI
2019United StatesMississippiGreenwood Springs0Tornado outbreak of April 13–15, 2019 – This EF2 tornado tracked through wooded areas and downed numerous trees. A few homes sustained roof damage as well. In a later analysis published in the Monthly Weather Review, it was noted that, "this tornado produced forest devastation and electrical infrastructure damage up to at least EF4 intensity" with winds up to 182 mph.Anthony W. Lyza, Barrett T. Goudeau, Kevin R. Knupp
