Significant Tornado Events

I did one of fancy motion panorama thingies on an okay quality copy of the sheriff’s video of Pampa which is pretty notorious for the shaky handheld video, and while I wish Grazulis could’ve provided an example on how exactly he came to that 300MPH rating, I can’t say that I disagree, the motions on this are on par with Duke Evan’s video of Andover.

Here's 2 Pampa videos in much better def, the first one is remastered version of the sheriff's video, try a motion thingy with higher quality.

1.


This one's a compilation of various tapes, including the sheriff's:

2.


Chuck Doswell's footage from that day, at around 1:13 is when the tornado enters the industrial park & you can really see the drillbit motions on the lower left side of the funnel, maybe if you compress this video you may see them even better. Crazy stuff.

I've always wondered how far the pickup trucks thrown by Pampa flew....my guess is anywhere from 200-500 yards.
 
No one has posted Greenfield images in here yet so i'll share all mine. If anyone has any that I don't I would love to have them!

Snapped Basement walls. Notice the giant chunks in the foreground.

Some contextual damage which confirms the explosive power of the Tornado. Keep in mind the tornado was a few hundred meters wide and was moving at 55mph. It probably never spent more than 10 seconds over one area:GOJB_syWAAAf8ai.jpg
manhole cover wasn't just thrown. but lost. I wonder where it ended up.

snapped foundation and debarked trees.

These parking stops have been the center of a lot of debate. Some people have said they were atypical and had failure points where grooves were left for forklifts. This is an incorrect assumption. The width is wrong, and is too wide for forklifts. This is just a case of solid, reinforced concrete snapping off of its anchor bolts. You can see the anchor bolts sticking up where the parking stops were.

This home was built on a CMU foundation, but here you can clearly see where multiple blocks were snapped in half rather than failing between blocks. Also note the debarked trees in the background.

A piece of someone's front porch or basement foundation that was tossed. You can use the car or the junction box on the ground to the left for scale. This is a 3000 LB+ slab of concrete.

A pile of shredded debris piled around a debarked nub of a tree.

A lot of these Greenfield pics remind me of Joplin....this thing was definitely EF5.
 
The best drone footage of the immediate aftermath



The best video showing the insane damage gradient. Mere yards separated the "relatively untouched" and "completely destroyed"



"Cinder block building gone. Auto lift with bolt in concrete pulled out."



Video from 30 days later paints a clearer picture of how many buildings were destroyed.

Well, the fact that DOW measured windspeeds in the Greenfield tornado went well past an EF5 (and even an F5) rating pretty much makes that indisputable...

Although, structurally, I do have to say there are a few homes from Greenfield that stand out to me as *possible* EF5 candidates. This first one was on the edge of Greenfield itself, hit just as the tornado was entering town. Completely swept off its poured concrete basement foundation, but slapped with a low-end EF4 rating and strangely listed on the DAT as "all walls collapsed" instead of "slab swept clean". No photo attachments either, so the level of anchoring is unknown.

This second one is from a more rural area southwest of town - I have seen ground level photos of some of those, and they weren't well constructed. But I never figured out which of the ground level photos (if any) show this particular home:

On the topic of 4/27/11, I'd love to find more damage pics from Enterprise, MS/Uniontown, AL and Cordova. Given what we know about Hackleburg actually being two tornadoes I wonder if there's evidence of Cordova or Enterprise being 2 or 3 separate tornadoes that were erroneously lumped together.

Do you happen to have any damage photos from Cordova? Im mainly looking for contexuals or the most violent damage in general. Would be much appreciated!

Scouring. In the second photo, there's debarking and a mangled tractor as well:

A newly (at the time) constructed home that was destroyed:

Looks like one of the 2 most wished photograph tornado (tri state and Plainfield) finally has a photographed

what appears to be 2 images of the wall cloud with the bottom one showing the tornado (its hard to see if the top one has it or not)
1727020390522.png


looks very similar to the bridge creek 1999 tornado when it had that F0 satellite orbiting around it.

edit(seems it might not be the F5 tornado but the third tornado from this mesocyclone , the Plainfield tornado was the 5 tornado form this meso, base on the time, however this does seem to be the same meso that would make this tornado)

This is from Paul Sirvatka's video, which IIRC was taken very near the airport in Sugar Grove.
