Significant Tornado Events

There are some decent pics of the Berryville aftermath.

Anyone have photos of the "plausible EF5" homes swept away by the Chickasha-Blanchard tornado? All I could find are two photos, one of a home that clearly had anchoring issues (no nuts or washers) and a photo that is too low resolution to be conclusive. Regardless however the contextual damage from this tornado was extremely violent and likely well into the EF5 category.

Today is the 32nd anniversary of the F4 that went down Airport Road in Huntsville during rush hour.

Pictures of the Devastation from the Airport Road Tornado

This tornado was responsible for taking 21 lives, but is indirectly responsible for saving thousands upon thousands of people in the years after. This specific tornado is what pushed Bob Baron to start his company, which innovated things like storm tracks with times of arrival, street-level mapping with radar, lightning data overlaid with radar, algorithms to interrogate and track gate-to-gate shear, and many of the other things that have become the industry standard when doing broadcast live severe weather coverage.

Some rare photo from Greensburg. As I see, ground was scoured in the first picture and railway in the fourth picture was likely bent slightly?

This is the plausible EF5 home.

 

[TH2002]

I have heard that the Picher tornado damaged or dislodged part of a home's foundation. Is this the correct photo?

 

[TH2002]

This is the plausible EF5 home.

It looks like the amount of debris left/on near the foundation would mitigate an EF5 rating unless the home was "exceptionally" well-constructed. I do however note what looks like debris granulation near the foreground, and if it is, it's some of the most incredible debris granulation I have ever seen.

Some of the anchor bolts were missing washers and the sill plate attachments used cut nails.

Yes, the debris granulation was Incredible in this place, even the brick itself was split apart. Chickasha was one of only several tornados that can scour asphalt from several roads continuely.

I did note anchor bolts missing nuts and washers on the first photo I posted, and I presume the photo of the house you posted was a different one? Or is it the same house before and post cleanup?

Off the top of my head the only other tornado I can think of that granulated bricks in such a fashion is Smithville.

That’s not the one unfortunately. In the photo that shows it, the foundation is noticeably thin, but is clearly buckled. I think a bathtub is visible in it too? It’s a shame that the photos on the NWS event page no longer work.

Okay I think I know the photo you are referring to. Assuming this is the right one, I never knew what it actually showed:

Yup that’s the one. There’s a second angle where you can see a portion of tiled concrete floor cracked and buckled too.

Some damage photos from the Greensburg KS EF5 which I don't think they had ever been published by someone else, mostly in rural areas.I cannot confirm whether these photos are belongs to the south of the town or to the north of the town.

One more mangled car.

Well that certainly makes the Greensburg tornado damage higher than marginal EF5.

For many years I had doubts about the EF5 rating for Greensburg tornado but these damage photos certainly prove it was definitely an EF5 tornado.

Yes, I never buy the idea that Greensburg was marginal EF5. At least Rainsville was much marginal than that.
The reason was:
1 peak intensity likely reached south side of town with significant scouring and 4 well built EF5 rating houses swept clean with trees totally debarked.
2 Tim Marshall mentioned that the high school in town was the strongest he ever seen and almost got EF5 rating itself. We know how many tornados he surveyed and how many violent and EF5 tornados came across school in the past.
3 Theoretically, giving the same wind speed, It's harder for tornados with big RMW do same level damage with small one, especially structure damage. Greensburg still holds the widest EF4 path since EF scale began.
4 Now we know this tornado capable of bent railway and throw cambine and harvest around.
So It was at least not a marginal one to me.

scouring south side of the town.

Another fire hydrant damage, not like the former one, this one likely not simply knock down by debris.
