Powerful Tornadoes Outside the United States – Violent Tornadoes in France, Russia, South Africa, Poland, Canada and Japan

In 2012, a powerful, long-tracked tornado swept through the Polish countryside - causing one fatality.

In 2012, a powerful, long-tracked tornado swept through the Polish countryside – causing one fatality. Southern Poland is one of several regions across the world that are occasionally prone to violent tornadoes.

□ The United States experiences more violent tornadoes than the rest of the world combined. In spite of this, the atmospheric ingredients needed to form rotating thunderstorms are present across the world. Strong tornadoes have occurred on every continent except Antarctica. Bangladesh has seen more tornado related deaths in the last three decades than the United States, and some of the most violent tornado footage ever recorded has come out of Eastern Europe. Few countries keep meticulous records of severe weather events like the US, so information is limited. With the data available, I have compiled a list of some of the most powerful tornadoes that have occurred outside the United States since 1940.

10. JAPAN – Saroma, Hokkaido – November 7, 2006

There are two known photographs of the Saroma tornado as it tore a narrow but intense path through a residential area in the Wakasa district.

Most tornadoes in Japan form in the outer rainbands of tropical cyclones, though some are spawned within supercell thunderstorms with pronounced hook-echos. On November 7, 2006, an unusual supercell thunderstorm developed over the Japanese island of Hokkaido. A rope-like tornado formed a few miles south of the island’s northern shoreline and tore through two dozen buildings in the Wakasa district of Saroma. Two homes were completely leveled and nine people were killed in the destruction of a two-story pre-fabricated building. Airborne projectiles penetrated the walls and roofs of homes, and cars were thrown more than 30 yards. Damage surveys later determined that the tornado was of borderline F2/F3 intensity in the Wakasa district. The Saroma tornado remains the deadliest tornado to strike Japan in the past 70 years.

The tornado left a narrow streak of damage through a strip of buildings lining a highway. All nine deaths occurred in the destruction of a large pre-fabricated apartment building (visible at bottom left).

Heavy damage in the Wakasa district. Airborne projectiles penetrated buildings and left battering marks on standing structures.

9. POLAND – Zimna/Wodka, Strzelce – August 15, 2008

Two views of a mutli-vortex tornado that caused three deaths in Poland in 2008.

A dozen tornadoes tore through southern Poland in the summer of 2008. The most significant tornado of the outbreak was a large, multi-vortex storm that travelled over 60 miles. The tornado tore through an agricultural area and destroyed dozens of rural homes, killing three people. Vehicles caught in the tornado’s path were swept off roads and mangled. Damage photographs indicate the tornado likely caused damage of low-end F3 intensity, although some unofficial sources cite the tornado as an F4. Geographically, Poland is situated in one of the most tornado prone regions in Europe and is one of the few places outside the United States where large tornadoes occur on a semi-regular basis.

The deadliest tornado during the August 2008 tornado outbreak leveled homes in southern Poland. The tornado hurled vehicles through the air as it crossed a highway near the Slovakian border. Light-poles on the highway were bent to the ground.

8. SOUTH AFRICA – Duduza, East Rand – October 2, 2011

The Duduza tornado killed one person as it tore through rural areas outside Johannesburg. Video of the tornado shows rotation and structure possibly consistent with a storm of F3 or F4 intensity.

A strong tornado developed in rural areas east of Johannesburg in the spring of 2011. The powerful storm tore through a working class neighborhood and destroyed several dozen homes. Some of the buildings devastated by the tornado had thick stone walls that may have added significant structural strength, although the overall construction of the area was substandard. One person was killed and several more were injured. South Africa is one of the few areas outside the US that consistently sees powerful and deadly tornadoes. More than 100 people have been killed by tornadoes in South Africa since 1948.

7. Tsukuba, Japan – May 6, 2012 

In 2012, a powerful tornado left a 10-mile path of destruction north of Tokyo, Japan. The narrow tornado swept over dozens of multi-level apartment buildings and caused more than $50 million in damage.

In 2012, a powerful tornado left a 10-mile path of destruction north of Tokyo, Japan. The narrow tornado swept over dozens of multi-level apartment buildings and caused more than $50 million in damage.

In the late-spring on 2012, a supercell thunderstorm spawned a violent tornado that touched down northwest of downtown Tsubuka City, Japan. The tornado slowly intensified as it twisted through a rural area, uprooting trees and damaging agricultural buildings. Video evidence indicates that the tornado remained fairly narrow, less than 50 yards in width, as roared to the northeast at 30mph. The tornado reached F3 intensity as it tore through an industrial area, destroying wood homes and hurling cars through the air. A teenage boy was killed in the destruction of a home, and more than two dozen people were severely injured. A damage survey later revealed that several homes were swept completely away, though the construction quality did not warrant an F4 or F5 rating. In one area, a home’s concrete foundation was ripped from the ground and flipped upside down (“Quick report on…”, 2012). The severity of the damage was unprecedented in Japan, a nation where few storms surpass marginal F2 intensity.

6. FRANCE – Hautmont, Nord France – August 3, 2008

The Hautmont tornado was very narrow at certain points in its life and yet strong enough to completely obliterate a two-story home. Most homes in France are built with substantially heavier materials than US homes and may require stronger winds to be destroyed.

During the summer of 2008, a powerful supercell thunderstorm developed over the farmland of northern France. An intense tornado touched down and swept through 12 miles of agricultural land near the Belgium border. The hardest hit town was Hautmont, where three people died and several large homes were completely leveled. The death toll included the town’s deputy mayor and his wife, both of whom were killed when their large home was flattened. The worst damage was generally confined to an extremely narrow path less than 50 yards wide. One unlucky home was almost completely swept away while two neighboring homes remained comparatively unscathed. Additionally, large trees were stripped of leaves and branches and metal posts surrounding a soccer field were bent to the ground.

Some meteorologists believed the tornado deserved an F4 rating, but the ever-conservative French meteorological board gave the tornado an F3 rating. Outside the United States and Canada, the Hautmont tornado likely caused the most intense tornado damage ever clearly photographed.

5. CANADA – Barrie/Grand Valley, Ontario – May 31, 1985

On May 31, 1985, an unprecedented outbreak of violent tornadoes swept across Ohio, Pennsylvania, New York and Ontario. In Ontario, the tornadoes killed 12 people and caused 200 million dollars in damage. The deadliest tornado swept through the town of Barrie at F4 intensity and killed eight people along its six mile path. The deaths included a mother and child who were killed when their Crawford Street home was swept away, leaving nothing but “a concrete pad” (Bruineman, 2010). Vehicles and bodies were blown several hundred yards, and several large factories were completely leveled.

A second violent tornado formed in another massive supercell just south of the Barrie storm and devastated areas near Grand Valley. The Grand Valley tornado travelled 62 miles – the longest path ever surveyed in Canada – and was potentially even more violent than the shorter-lived Barrie tornado. The storm caused F4 damage and killed four people – two deaths occurred in destroyed homes, one in a vehicle and another man died of injuries in a destroyed shed.

Severe damage caused by the 1985 Barrie tornado. An even stronger tornado may have formed in Ontario that day, only a few miles south of Barrie.

4. CANADA – Edmonton, Alberta – July 31, 1987

The most famous view of the Edmonton tornado of 1987. The massive tornado was remarkable for forming so far north – more than 300 miles above the US-Canadian border.

The Edmonton tornado was massive even by tornado alley standards. It remains the northernmost violent tornado in history, and the second deadliest tornado in North America during the 1980’s. It touched down to the south of Edmonton in the community of Mill Woods and roared almost due north through eastern sections of the city. Had the tornado formed a few miles farther to the west, it may have become one of the deadliest and most damaging tornadoes in world history as it would have torn directly through the high-rise district of downtown Edmonton and impacted more than 10,000 homes at F4 intensity. The tornado was at maximum intensity as it passed through an industrial area, completely leveling dozens of large businesses and killing 12 people. The tornado then crossed the North Saskatchewan River and paralleled a housing subdivision, where dozens of homes were destroyed. Near the end of its life, the tornado narrowed and tore through the Evergreen Mobile Home Park, killing 15 people. Overall, the tornado caused 27 deaths and more than 300 million dollars in damage.

Some articles have discussed the possibility that the tornado may have reached F5 intensity. Most of the residential damage caused by the tornado was in the F2/F3 range, primarily because the tornado travelled parallel to a housing subdivision without ever actually passing through it. Damage in the industrial area was more intense and indicative of high-end F4 intensity. No homes were swept away and no vehicles were reportedly carried more than 200 yards, so it is unlikely the tornado will ever be upgraded to an F5.

The Edmonton tornado had narrowed and was near the end of its life when it struck the Evergreen Mobile Home Park. More than 100 mobile homes were destroyed and 15 people were killed.

3. CANADA – Tecumseh, Ontario – June 17, 1946

The Tecumseh tornado on June 17, 1946, was one of the strongest tornadoes ever recorded outside the United States.

In 1946, an extremely powerful tornado swept through southwest Ontario and caused possible F5 damage in the town of Tecumseh. The narrow and fast moving tornado first touched down in Michigan and rapidly strengthened as it crossed the Canadian border. Seventeen people were killed as homes were reduced to bare foundations. There were multiple deaths in several households and many of the bodies were stripped naked and thrown more than 100 yards. Much like the Elie F5 tornado 60 years later, the Tecumseh tornado was extremely compact and powerful and never took on the “wedge” appearance common to violent tornadoes in the United States. When the Fujita Scale was developed in the 1970’s researchers attempted to rate past tornadoes via the available damage photographs and newspaper reports. The Tecumseh tornado was given an F4 rating but left some damage indicative of F5 strength. One home was so thoroughly destroyed that even its underground basement walls collapsed and were partially blown away.

The home at upper left was destroyed and swept away in the Tecumseh tornado.

View of a home that was completely destroyed by the Tecumseh tornado. The basement walls collapsed, causing a landslide of dirt to partially fill the empty cellar. Though the quality of construction is unknown, damage of this severity hints at possible F5 winds. The narrow tornado was very selective, leaving homes across the street with little damage.

2. CANADA – Elie, Manitoba – June 22, 2007

The Elie, Manitoba tornado was filmed as it ripped an entire frame home from its foundation and tossed it into the air. The tornado meandered around the town of Elie and rapidly strengthened near the end of its life as it narrowed and began to dissipate.

The only tornado outside the United States that has officially been given an F5 rating formed east of Winnipeg, Manitoba, in the summer of 2007. The storm spun out of a low precipitation supercell and touched down a few miles northwest of the town of Elie. The tornado executed several counterclockwise loops as it meandered to the west of the small community. Near the end of its path, the tornado narrowed and intensified as it turned north towards a row of houses on Elie street. Video footage shows the violent tornado ripping one home from its foundation and lofting it into the air. The videographer also caught a van being hurled more than 200 yards from where it originated. Three homes were swept from their foundations, one of which was later determined to have been well-constructed. The complete destruction of the well-built home and the violent motion recorded on film were the basis of the F5 rating.

1. RUSSIA – Ivanovo, West Russia – June 9, 1984

Next to nothing is known about the West Russian tornado outbreak of June 1984. Satellite images show an impressive series of large and well formed supercell thunderstorms the day the outbreak took place in the vicinity of Ivanovo.

Very little information is available on a violent tornado outbreak that swept through areas north of Moscow in the summer of 1984. The Soviet Union had not yet disbanded and few details were leaked to the international media, despite the fact that the outbreak occurred within the home video age. The outbreak was the result of a series of violent supercell thunderstorms that travelled north-northeast at speeds greater than 50mph (Finch and Bikos, 2012). Local newspapers reported that massive hailstone, some over 2lbs in weight, fell over the affected areas.

Sources indicate that 400 people were killed, with most of the fatalities likely the result of a single tornado that tore through the town of Ivanovo. A French research article describes how the tornado threw cars long distances, lifted a 350-ton operating crane and leveled “steel-reinforced” buildings. According to the same article, the Russians unofficially awarded the tornado an F4 rating, although some of the damage was indicative of F5 strength. The article also states that another tornado that affected the town of Kostroma was given an F4 rating but may also have reached F5 strength. An english-language article describes how the Ivanovo tornado scoured pavement from a highway and hurled a 120,000lb water tank several blocks.

Archived satellite images from June of 1984 show an impressive severe weather set up reminiscent of large outbreaks in tornado alley.  If the reports are all true, then the outbreak was an unprecedented event and astoundingly violent for an area generally accustomed to tornadoes only capable of inflicting F1 and F2 damage. Pavement scouring and the movement of massive industrial equipment is likely indicative of winds of F5 intensity. At the same time, media reports from the former Soviet Union are notoriously unreliable, so the available information is by no means “proof” that the outbreak produced tornadoes capable of causing EF5 damage.

□ Over a long enough time scale, over many generations, violent tornadoes undoubtably touch down in every corner of the unfrozen world. Rotating supercell thunderstorms have been documented via doppler radar off the coast of the Hawaiian Islands, far from any traditional continental severe weather setup. The chances of an F5 tornado forming over the open ocean, or England, or Japan, or the rest of the non-arctic landmasses is exceptionally small. But weather patterns, and extreme natural events, are sometimes separated by hundreds, thousands, or even millions of years.

In Hawaii

In March of 2006, an unusual severe weather set-up formed in the open ocean near the islands of Hawaii. Radar documented a well-formed supercell thunderstorm, likely with a large tornadic waterspout, 100 miles off the coast of the Big Island. Such discoveries highlight the existence of strong tornadoes, however rare they may occur, in locations unaccustomed to severe thunderstorms. (Image by Nash, Rydell and Kodama, 2006)

  1. Strongest tornadoes in the Netherlands in the 20th century:

    1. Neede (GL), Jun 1 1927 = F4, 10 death
    2. Oostmalle (Belgium) – Chaam (NB, Netherlands), Jun 24 1967 = F3/F4, 2(4) death
    3. Tright (GL), Jun 24 1967 = F3, 5 death
    4. Zeeland (NB), Aug 10 1925 = F3, 4 death
    5. Borculo (GL), Aug 10 1925 = F3, 4 death
    6. Kootwijk (GL), Aug 23 1950 = F3 (F4?), 0 death

  2. The Russian tornado outbreak mentioned here has always fascinated, because so little information is available on it and yet the sheer violence of it puts many events here in the states to shame. I highly recommend this article on it: http://www.ejssm.org/ojs/index.php/ejssm/issue/view/37. It has probably the most information available in English on it that we’ll have for some time.

  3. Sometimes I wonder if tornadoes (or severe weather in general) in prehistoric times would have been more or less powerful than tornadoes today. For all the tornadoes Americans have encountered or been impacted by, you have to wonder what the indigenous populations witnessed or had to put up with…maybe they were among the few to witness a “once in a millennium” events.

    • I’ve often wondered about that. Given the variability of the climate I’m sure that, at some point, conditions were favorable for even more extreme outbreaks than we’ve seen. Heck, even some of the older outbreaks that we do know about (1884 Enigma, 1932 Deep South Outbreak, 1920 Palm Sunday and a bunch of others) could very well have been much more intense than we know. Oh, how I wish we had the technology then that we do now..

  4. 1984 seems to have been an exceptional year for tornadoes…the Carolinas outbreak, Barneveld, and the Western Russia outbreak…I’m sure it’s just a coincidence, but I find it interesting how it occurred the day after Barneveld.

  5. I have sometimes thought that many of the impressive feats attributed to the Ivanovo-Yaroslavl event might have been either exaggerations or misunderstandings reported by the newspapers from what their employees were told. On the other hand, if the reports are all true, than this was probably one of those things that happens once a millennium, or 500 years, or whatever length of time you like.

  6. I have never bought the Ivanovo super tornado. It’s hog wash. The Russians gave it an EF4. I don’t understand why it is given such attention when nothing is known about it. I’m sure that since EF4s almost never happen over there, that it probably did seem like a mega-tornado and was prone to exaggerations.

    • I agree about the Ivanova tornado. Due to the recently updated wikipedia article on the outbreak (which is very likely ripe with exaggerations and assumptions) some people are now saying the Ivanova tornado was “the strongest tornado of all time.”

      I do not believe the tornado(es) reached EF5 intensity, or maybe even EF4 intensity, and I do not believe they caused hundreds of deaths. If I see a shred of convincing evidence like a damage photograph or detailed newspaper account, I might change my mind.

      • I am an editor on Wikipedia. If you could point me to some good source material I might be able to fix a few things.

      • The Ivanovo (not Ivanova, as is commonly misspelled) F4 rating was assigned in 1987, at a time when the Soviet authorities carefully minimized disasters. The KGB and even scientists were obliged to minimize the number of deaths in a nation that was highly sensitive to foreign scrutiny of its (decaying) infrastructure, poor weather-warning system (the USSR had no modern radar system in 1984), etc. The 1984 outbreak would not be an exception; the Soviets also initially covered up a contemporaneous event, the Chernobyl nuclear disaster. Frankly, I would be more inclined to trust the (more-numerous, though not entirely authenticated) extreme reports than the officially-commissioned, albeit “scientific”, report that assigned an F4 rating and only blandly describes some mild tree damage and unroofed buildings. Even the Soviets didn’t hide the fact that the tornado killed quite a number of people.

      • Good catch, I used both “Ivanova” and “Ivanovo” interchangeably and didn’t even notice it.

        As for the tornado’s intensity, it’s just so bizarre since western Russia rarely ever has F2 tornadoes, nevertheless strong or violent tornadoes. The idea that an outbreak in the area spawned two F5 tornadoes within miles of each other seems a little fishy to me, though it is certainly not impossible.

        The complete lack of damage imagery, media reports and citations regarding the storm’s incredible feats leave me feeling that the specifics of the outbreak are not yet verifiable.

      • Actually there was 3-4 violent tornado in Soviet Union history, and 49 violent tornado(F4) in European history, F5 is’n Impossible thing.Also, there is 6-8 violent tornado in China since 1949.

      • “the strongest tornado of all time.”

        When it comes to EF5 damage there is the 1997 Jerrell tornado and there is everyone other tornado. Been other tornadoes with higher winds or much longer path, a lot more fatalities, etc, but none with so much damage in such a concentrated area including a 95% kill ratio of people above ground.

  7. Is there any reason the 1973 San Justo, Argentina tornado is not included in this list? Quite a few photos of the damage are available online, and it does seem to have been pretty intense.

    • Two reasons. First, this isn’t supposed to be a categorical list of the strongest tornadoes, just several strong to violent tornadoes that formed outside the US.

      Second, I had not seen the pictures of the ’73 storm when I made this post. There are several I’ve learned of since then that deserve a high place among a ranking of the strongest international tornadoes.

    • The Piedras Negras tornado would definitely belong on a list of violent tornadoes outside the US. It was very likely more violent than its deadlier counterpart across the border in Texas – probably a legitimate borderline F3/F4 tornado.

  8. You should also look into the Veluwe F5 tornado in the Netherlands in 1950, the F5 Montville tornado in France in 1845, the F5 Palluel tornado in France in 1967, and the F5 Montello tornado in Italy in 1930🤔

    • Jaimy – It’s been awhile since I’ve edited this list. The 1930 Montello tornado and the 2015 Mira Italy tornado both caused what looks to be solid F3/F4 type damage, though there are very few images of the Montello aftermath so it’s hard to make a judgement. I’ve looked at pictures from the 1967 tornadoes in France and didn’t see any damage that appeared above an F3 rating (my personal opinion). Tornado rating scales were not around pre-1970, so all tornadoes before that are unofficial F5s, often based on a few old newspaper accounts which are prone to embellishment (the Wikipedia article on European tornadoes is very anecdotal and not a good resource). I try to stick to tornadoes that I can analyze more closely through scientific articles and damage imagery. If you have any good sources regarding these tornadoes I would love to see them! I’m very interested in violent tornado outbreaks outside the US.

      • Yikes, I’m very interested in damage pictures and analyze it more. Do you know that I have lot more knowledge of tornadoes in the America. I think a deadly F5 tornado slammed Uhall, Kansas is the worst damage, but still unsure. I am unsure because too much another tornadoes devours a hundred percent entrie house. But I am extreme suprise that Jarrell, Texas F5 tornado are so powerful that entered Double Creek road and blown all house away. Otherwise most impressive damage of tornado is grasses. The grasses has rich of soil but tornado carried the heavy rain to make ground so wet and burrowing even the nearly 750 feet long road are completely eaten. This is my actually favorite tornado. The strongest wind ever recorded and being killer tornado occured on Monday, May 3, 1999. An F5 tornado entered Bridge Creek-Moore top intensity occured there, the winds reached 301+20 MPH. Sadly Happen twice, on Monday May 20, 2013 an killer high-end EF4 or EF5 tornado cut 18 miles in its path.

  9. San Justo was probably nore violent or just as violent as Ivanovo, it did some really incredible damage. I didn’t even know S. America could get F3+ tornadoes! I also found some Wikipedia pages on some a few F4/F5 tornadoes in France, Germany, Austria and Italy.
    Several events that caught my eye were the August 1845 Montiville F5, the June 1924 Budapest, Hungary F4+, the June 1927 Neede F4+, the July 1930 Montello F5 (lists 500kph winds), the July 1931 Poland F4+, the August 1950 Netherlands F5 (T10), the June 1957 Italy F4+ (T9-T10), May 1960 Ukraine F4+, the June 1967 France F5, the June Ivanovo & Kostroma, USSR F4+, and if were including areas outside of N. America, we should also include the San Justo, Argentina F5.
    Great Article anyways.
