Significant Tornado Events

Those tree damage near the cabin are not puzzling to me. Tree damage here was given EF4 rating and it was the right call for sure. These trees were on the upwind direction from the house so there was no debris at all, even no tree stand in the upwind direction, though some trees still get debarked If you choose the right angle. Those all large harwood trees. Grass scoruing in the center line was apparent, though not very remarkable.

The ground scouring when it was approaching the trees was very intense

i’m talking about the extremely intense tree damage

 

[speedbump305]

Am i the only one who thinks Bassfield produced the most intense tree damage i’ve ever seen? Yes even more intense than Smithvilles softwood tree damage

This survey report provides some details in the rare tornado event in Nepal in 2019. There were actually two tornadoes: one in mountainous national park area and another in plain area. The one in plain area has a track of 43.6km and max width of 695m. The author suggested an intensity of EF3.

There seems to be many very rare tornadoe event around the world in 2019.

Rare “Tuscaloosa looking” tornado in Turkey in January


Havana Cuba EF4 tornado in Januarry, strongest tornado in Cuba in at least 80 years.



extremely rare tornado in South Korea in March, likely EF2 level tornado


Historic Nepal tornado in March. Strongest and the only recorded tornado in Nepal history. In June this year yet another tornado observed in Nepal.


Nigeria tornado in April , maybe the only tornado that I have heard in this county


Exceptionally rare tornado event in Chile in May
There was an article about this event just came out last month:

The Chilean Tornado Outbreak of May 2019: Synoptic, Mesoscale, and Historical Contexts

Abstract In late May 2019, at least seven tornadoes were reported within a 24-h period in southern Chile (western South America, 36°–38°S), including EF1 and EF2 events causing substantial damage to infrastructure, dozens of injuries, and one fatality. Despite anecdotal evidence and chronicles...

Historic Kaiyuan EF4 tornado in July in China, strongest big city tornado in China since 1969



Two F3+ tornados in November/December in South Africa, strongest tornado in this country in at least 10 years. Another EF3 tornado occurred in SC again in 2020 January.


I may still missed some tornadoes this year.

The deadliest and one of the strongest tornadoes in Saskatchewan history was the 1912 Regina tornado. The tornado touched down 10 miles south of town and moved N through farmland. Entire farms were leveled in the countryside with some farmhouses being swept away. Debris was scattered for miles from the destroyed buildings. 3 miles south of Regina, the first fatality occurred on a farm when a guest was killed. This farm was reportedly completely swept away with "even cement foundations ground into powder" (the foundation part was probably not true.) The tornado was rather narrow when it tore through the city of Regina, about 165-300 yards wide, but it was very intense. Numerous buildings and homes were completely leveled with some being completely swept away. The tornado reportedly dissipated 7 miles north of town.

Quite a few of these photos show granulized debris, while it's clear some cleanup has occurred this thing was definitely very intense. I haven't seen many damage photographs from this event before and I'm really impressed.

We are overdue for another major tornado strike/disaster in Canada. Last one was Pine Lake AB in 2000.

From the 1940s through 2000s they generally happened on average once per decade or so (Windsor 1946, Sarnia 1953, Sudbury 1970, Windsor 1974, Barrie 1985, Edmonton 1987, Pine Lake 2000).

 

[MNTornadoGuy]

Another violent Canadian tornado is the 1946 Windsor tornado. This narrow but violent tornado tore through Windsor Ontario leveling multiple homes with some being swept away. 18 people were killed by this tornado.

Wasn't there a big one at Woodstock in 1979?

Yes, although I was only including ones with 5+ fatalities.

Russian trees are also rather easy to snap or uproot.

I'm working on a translation of Gottlob Burchard Genzmer's report on the 1764 Woldegk tornado, which is the first "official" F5. I think it's kind of ridiculous to rate a tornado based on a damage report from 1765, but the ESSL seems to disagree. Anyway, I couldn't find an English version so I'm going to do one myself. I'll share it once it's done.

Interesting pictures, I made a previous post on it: https://talkweather.com/threads/significant-tornado-events.1276/page-62#post-49358

This tornado took a path very similar to the one from 4/3/74 that struck areas not that far from Tecumseh and Windsor.

I'm not sure of the construction quality of the homes it swept away (or caused the basement walls to actually cave in) but if they were well-constructed that would be a clear indicator of F5 winds.

I agree with you. They also gave an F5 rating to a tornado from 1800. Trees were reportedly completely debarked and homes destroyed but that's it.

If only photography was invented then we'd be able to know for sure the intensity of the Woldegk tornado, but oh well. It does seem violent but hard to know given the time period. I have some PDF files on tornadoes in medieval Europe (particularly in the Czech region), turns out they may have been more common than previously thought. I'll post some links if others are interested.

Actually that 5th image shows impressive softwood debarking. that’s what it looks like

There's one very interesting tornado event that I haven't heard any mention of outside of Tornado Talk. It was a very short-tracked, narrow, but devastating twister that tore the community of Hamlet, a small subdivision near Limerick, Pennsylvania at nighttime on July 27th, 1994 with devastating results. A few homes were completely leveled to the ground, and a family of three died in one of them. The tornado didn't even last for two miles. but was by far the strongest of a high-end Mid-Atlantic Tornado event (they don't see many significant tornadoes to begin with), which resulted in several significant tornadoes across Maryland and Pennsylvania
