Another overlooked tornado is the Roanoke, IL tornado of 2004. Completely demolished a manufacturing plant. Some of the most impressive damage to an industrial building.

The car damage of Roanoke tornado was also quite intense and the video appearance of this tornado was impressive.

"Philadelphia style" is a reference to this:



This tornado struck areas near Philadelphia, MS during the April 27, 2011 Super Outbreak. These trenches were up to 3 feet deep in places.

Thank you. Now I remember that gouging was mentioned.

My jaw dropped when that one man jumped down into the hole!

The damage to the land in that video does remind me of images of liquefaction and lateral spreading (like the first one under "Cyclic Mobility" here, though those cracks paralleling the shore are something else related to earthquake effects; I just mean the whole area change).

In the video you shared, look at how sod clumps sit "high and dry," for instance, as though what was under them flowed away (and probably up and outwards in that situation).

Just because powerful tornadoes leave a muddy path doesn't mean that all came from rainwater -- could be from the soil, too, though I can't imagine how to test that.

This is complex, but I did find a reference for tornadoes transferring energy to the ground: perhaps non-seismologists could get access to the whole article through a university library?

Here's a list of papers that cited the above 2001 article, including a fairly recent one from the American Meteorological Society.


What do experts say about these effects from the Smithville EF5 (photos from this post)?

All I can say about the Smithville tornado is that it's touchdown point and much of its initial path was just east of a man-made waterway, so possibly the soil was a bit looser due to being in close proximity to a body of water but ultimately I doubt it. This scouring occurred right after it reorganized itself and went multivortex, so likely it was from one of an intense suction vortex, much like the Philadelphia ground scouring.

Only in a few cases that a security camera can survive a violent tornado and here was some of them and the aftermath of the places that the camera was. These kinds of video had a full representation of how scray inside a violent tornado.
2008 Pakersburg IA EF5 First State Bank


I am very sure that the beginning of this video is some of the strongest wind Ihave ever seen in all kinds fo footage, TC or tornado.
aftermath: the bank was rated EF2

2011 Joplin MO EF5 East Middle School


Joplin had several surveillance footage, this one in East Middle School probably the most famous one. It was rated EF2 with winds of 125mph

2012 Henryville IN EF4 Henryville Junior-Senior High School


There were much more different angeles can be found in Youtube. Damge photo showed clearly multi-vortex pattern(the gym right-below of the image can be damaged by a sub vortex). Damage here was rated EF4 I believe.
aftermath

2013 Washinton IL EF4


I don't know where this place excatly located and what's the rating of this house but certainly a scray video to watch.

2015 Rochelle IL EF4


Though not a security camera but easily one of the most scary tornado footage of all time, very sad that the man shot this video lost his wife.
aftermath:It was rated high end EF3

I once saw surveillance video from Moore Medical Center several years ago but can't find it now.

I find I am a little confused about when was the real starting time of Jarrell TX F5 torando,
Based on this paper:https://journals.ametsoc.org/doi/full/10.1175/MWR3301.1
The starting time was determined at 20:25.
But based on NCDC, the starting time was determined at 20:40.
It may depends on whether this long roped and tilted feature tornado being classified into the beginning of Jarrell tornado


It has been mentioned in NCDC database that eyewitnesses indicated the damage path may not have been made strictly by one tornado. Also in this video, we can see that rope tornado at one time looked like it was going to dissipate. But after a very short time, the tornado came back again and there seems like it had a a small chance that the circulation was constantly on the ground during this period.

Alright so I got some impressive photos of damage done in Palm Sunday 1965.

Some photographs of damage done by the Dunlap tornado:

I doubt this is a controversial opinion but I think both Dunlap tornadoes, Coldwater, Toledo, and Strongsville were all probably F5 strength. All five completely swept away several well-built structures.

Might as well post this classic video of the Andover tornado going through McConnell AFB...these people caught it up close & personal as it was just beginning to go into multivortex mode. They really have no idea how lucky they are that they weren't completely engulfed by it:

I work right over by where the Andover, KS tornado came through in 1991.
