I have some questions about Pampa Tx tornado 1995 as one of the most intense tornadoes in history. Despite the very impressive rational speed showed on videos, the damage to the factory was no more than high-end F3 level. The F4 rating involved the consideration of visual appearance. The visual appearance was shocking at that time because so little high-quality footages exist at that time. The vehicle damage was violent but not the tree damage. The overall damage level was not higher than Dalton tornado last year or Marion ND tornado 2004. So many violent rope type tornados had very impressive rotational speed showed on video since then but most of them don't have photogrammetric analysis didn't mean they were weaker.
Pampa did loft heavy industrial machinery hundreds of feet into the air. Though it still probably doesn’t deserve being on the most intense tornadoes of all time list.

Detailed analysis of Rainsville EF5 from tornadotalk.
It's interesting to notice the difference of the EF scale map between tornaodtalk and NWS, especially the part south of Rainsville. Certainly, the map of tornadotalk makes more sense to me.

MBS Damage like this south of Rainsville was labeled as 156 mph EF3 point on damage viewer was hard to understand.

I've only seen one of those videos before. Great finds!
I was a double major. Communications and English. Most of the English work at my school was research before the internet, so I kind of like doing it with the internet as my source. My interest in the parent storm is obvious. I need to find a new target for my passion but I have no idea what to work on. Anyway, I like doing it and I found all but one I had seen previously. It was storm chasers on Hwy 8 near 45 almost running into the tornado.

Remember that Villa from the 2015 Mira Italy tornado that was nearly leveled? Apparently, the construction quality wasn't very good as the mortar was old and very crumbly per the ESSL.

I’ve read this as well, but with that said, it’s still some of the worst damage to a sturdy brick frame structure of that size that I’ve ever seen. The damage to concrete frame homes elsewhere along the path was also pretty impressive.

It was classified as a weak brick structure by the ESSL. The structure was also built-in 1665.

Right, but if you read the notes from the surveyors for damage points along the path, you’ll see that the F4 rating at Villa Fini was actually a downgrade, and the presence of sandy mortar led to an F4 rating even though F5 was actually being considered for that structure.

Yes, it was, but I don't think a downgrade means it was near-F5 in intensity there. They probably were considering it to be a possible F5 damage DI from a distance but when they got up close and saw the major structural issues they realized it wasn't F5 damage.

Yeah agreed. I personally don’t think the Mira tornado had F5 potential based on the contextual damage I’ve seen, but construction over there is so different compared to the US, it makes comparisons a little more unclear. For example, this concrete and brick construction house in Mira was given an F4 rating based on the collapse of its second story, even the the whole building wasn’t leveled.

I wonder what the damage would have looked like if the same tornado had struck a modern US-style subdivision of cookie-cutter wood frame homes.

I believe the highest-end damage along the path of the 2015 Mira tornado was this masonry house with self-supporting precast reinforced concrete joists beams. Some of the reinforced concrete joist beams were found broken 54-109 yards away. The contextual damage in this area was supportive of a intense-violent tornado with concrete poles being broken off at ground level, trees were debarked and farm fields were scoured.

Wow! What’s the source for these? Would love to read more about it.

Does anyone know if there any cases of extreme damage from the 2016 Funing tornado typically seen in North American tornadoes such as ground scouring, severe debarking of hardwood trees, cars being thrown hundreds of yards and being mangled beyond recognition or wind-rowing of debris?

I'm sorry but if they want to actively restrict the free flow of valuable information by demanding payment for previously free articles out of nowhere then I don't shed too many tears when people do stuff like that. If they were only making new articles premium that would be one thing, but restricting access to already exisiting articles is another thing altogether.

There was definitely extensive debarking, as well as vehicles being badly mangled. I think our contributors from China likely have the best photos that show this, but I know of a few as well. Interestingly, whatever species of trees these are have reddish wood underneath the bark.

There was an F4 tornado near Venice in 1970 that produced some pretty intense damage. Trees were debarked, cars were thrown hundreds of yards and mangled, and heavy boats were tossed around.

Last year's Viterbo, Italy tornado was pretty intense based on some of the damage photos I've seen

Some damage pictures from the 2003 Franklin, Kansas tornado:
Franklintornadodamage-aerial.JPG
Aerial view of the devastation. Ground scouring and moderate wind rowing is evident.

Franklintornadodamage-chassis.JPG
A vehicle was stripped to its chassis, with the chassis found embedded into the ground.

Franklintornadodamage-scouring.JPG
Franklintornadodamage-scouring2.JPG
Extreme ground scouring occurred throughout the path, with disruption of topsoil as well.

Franklintornadodamage-pavement.JPG
The tornado reportedly scoured pavement from rural roads and this is the only image I can find of that possibly occurring (though I'm not sure if what we're seeing is actual pavement scouring or not)

Franklintornadodamage-debarking.JPG
Trees and shrubs that sustained severe debarking. Honestly more intense than many official F5/EF5's including Greensburg

Franklintornadodamage-home.JPG
A swept away home in Franklin (foundation visible behind the flag) with severe grass scouring in the immediate vicinity. This home was well-bolted to its foundation and one person died here.
