Hello, my name is Robert, I’m an archaeology graduate. I study tornado archaeology, and detecting tornadoes prior to the written record through archaeological methods. I also study how tornadoes have impacted settlement depopulated in the Southeast through the past 800 years.

@fatalcarcrash @Roman2413045124 @maxthepro1012 Normal growth is usually interrupted for about 30 years before the forest is healed. This can change in lots of ways, for example, forests heal much faster in the southeast than the Great Plains, probably just due to water availability.

@fatalcarcrash @Roman2413045124 @maxthepro1012 Thank you! My soil particle size estimations just come from comparing the sizes to observed tornadoes, rather than any fancy engineering wind rupture calculations. With over 30 known scars tested, I’ve got a big enough day to set to compare that to recorded strengths.

For those curious, here’s a quickly-made graphic that explains the process a bit.

RobertWx@Trough_Digging

In case ppl are curious, here the order of some modern scars I’ve tested: 1. Guin 74 2. Jarrell 97 3. Spencer 98 4. Hackleburg 11 5. El Reno 11 6. A random scar in SW OK from the 50s 7. Greenfield 2007* (EF3 after EF5) 8. Falkville 55 9. Birmingham 98 10. Xenia 74

@Roman2413045124 @maxthepro1012 Thanks! I appreciate it. Whats interesting is when you find several scars in a single probe. That happens a lot specifically in that MS-AL corridor. There’s some probes Ive pulled out there that have been hit by like four violent tornadoes in the past couple hundred years.

@ConnerStinesWx That being said, I have considered some ways. Especially in terms of archaeological sites. In theory, you should be able to find archaeological evidence of debris rowing. Such as artifacts continually being NE of structure footprints across a site.

@ConnerStinesWx That’s awesome! Good luck. It’s definitely more difficult in the plains. The southeast makes a really good subject area for me because of all the forests. This testing method relies on the continual presence of forests before during and after the tornado event.

@Roman2413045124 @maxthepro1012 Yep! Takes about 3 hours to do mile strip. I then isolate the tornado bed part in each positive test for further analysis. I don’t usually do full analysis on each test though, that would take forever. Moreso a random sample of the tests for soil particle size and organic content

@Trough_Digging @maxthepro1012 So you go out to these places and get soil deposits and test them?

@JigsawYessir @300MphEF5 I really appreciate that! I actually have a paper in peer review at the moment, and like 3 more I’m working on. Just trying to get my PhD done and stop getting distracted with new ideas and topics lol.

@Trough_Digging @300MphEF5 Thanks for the responsiveness! I was rambling to my wife about your research last night because of just how novel & fascinating it is (although she certainly didn’t understand or care quite as much). I’m anxiously awaiting publication & would love to assist if you make it to KY

@ConnerStinesWx Currently juggling like 3 things for my thesis. But so far it’s been more archaeology focused. Presented at the SAAs a couple times on the subject. I’ve considered presenting at some meteorology conferences, but wasn’t sure if people would be interested.

@Trough_Digging Nice! I’m excited to see what you find, I didn’t realize there were other people in the Archaeology/Meteorology/GIS niche. Sounds like you’re doing great work

@ConnerStinesWx Sweet, that’s really cool! My main research is actually on Mississippian lifeways and tornado impacts. Right now, specifically, the Moundville change from population center to mortuary center being caused by a tornado impact in the late 14th century.

@JigsawYessir @300MphEF5 Thats exactly it! These rankings are the averages across the whole scar. And all of them are hardwood based. I have seen some crazy granulation on softwoods before, but that doesn’t tell you as much.

@maxthepro1012 I have tested them. The next most intense scar was actually Tuskaloosa, between Tuskaloosa and Birmingham not any of the EF5s. Then Smithville, Rainsville, Philadelphia. The Philadelphia one was a decent bit weaker than many EF4s on the day.

@Trough_Digging Wow. You plan to test the 3 other ef5's of 4/27?

@mee_wx Maybe, but I doubt it. You need a decent amount of undisturbed land to be confident you’re looking at a scar, which is why I target national and state forests usually. Even things like plowing destroys the scar. This seems like a pretty populated and disturbed area.

I wonder, what the fuck happened here in 1682. I was looking through ct tornadoes and all it said was "locals reported a 3/4ths mile wide swath of downed trees. Is there a way that you could find the scar?

@t0rnadofx @Roman2413045124 @EMoriartyWX Not sure. I think people have suggested that but there’s lot we don’t know. But that’s why im hesitant to discuss it in my thesis.

@JigsawYessir @Roman2413045124 @EMoriartyWX I specifically target national and State Forest for their amount undisturbed land. I need a couple miles of disturbed soil to test for scars. Or at least be any confident they’re scars and not some isolated event.

@JigsawYessir @Roman2413045124 @EMoriartyWX I kind of just test randomly in undisturbed soil locations. Sometimes I’m looking for a specific historical tornado, sometimes I’m just testing an area. I’m sure there’s dozens of scars I haven’t found even bigger.
