It doesn't have much info so just don't worry about it. There used to be damage photos and the damage survey from Grand Forks, ND.Can’t see what’s there. Wants me to subscribe to see the content.

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

Finally, some before & after pics of the plant:

Thanks for this! Haven't read this before.Here is some information on how the Barnes County, ND formed. https://journals.ametsoc.org/doi/full/10.1175/2007WAF2006109.1
That is some pretty impressive vehicle damage.The car damage of Roanoke tornado was also quite intense and the video appearance of this tornado was impressive.

Your welcome. There used to be damage photos out there. One well-built/anchored home was reduced to a slab of concrete with very little to no visible debris left. Additionally a huge semi truck was flung 1/4 to 1/2 mile through the air.T
Thanks for this! Haven't read this before.
"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)?
What happened to them? Were they crushed by debris or sucked out of the basement? That is terrible.The Crystal Lake, Illinois tornado of Palm Sunday 1965 did this, and the entire family hiding in the basement was killed. Pretty amazing.View attachment 3393
I should have added that. They were crushed by the pickup, no joke. Some tornadoes just aren't survivable no matter what you do, it seems.What happened to them? Were they crushed by debris or sucked out of the basement? That is terrible.
I really do wonder what the basis was for downgrading them.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:
