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.

@BuffaloLaz57818 main datapoints when I create a scar intensity score. Particle size, modern forest density, organic %, and tornado bed thickness. Usually these correlate to each other well.

@BuffaloLaz57818 1. Yes for sure. That’s why it’s harder to find scars outside the eastern United States. Even forced areas are less depth so it’s harder to find them. 2. These are ranked by soil particle size mostly, as well as the thickness and content of the organic layer. I use 4

@BuffaloLaz57818 I think that correlates to wind speed, but how closely I’m not sure. I need more data, and need people smarter than me to explore it lol.

@BuffaloLaz57818 I think it is, personally I think it’s one of the best. But before it can be widely accepted as a way of measuring windspeed, it’s got a lot of trial through other people to go through. Right now, I think it’s best to think of it as a way of measuring the intensity of scar.

@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.

@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.

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

A quick post on the top 10 most intense scars I’ve tested: 1. A likely Mississippi scar from the 1500s. 2. An undated Tennessee likely scar 3. A likely scar from the 1700s in southern Indiana 4. The Guin 74 scar 5. Sulphur Rock AR 1929 scar

@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

@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.
