I’d worry more about the New Madrid. A while back i was a map that showed the result of an 8.1 or so on the NM. I’d be 300 ft underwater but my sister would have beach front property near Omaha.
They had a map but it has been taken down of that. I wish I had printed off a copy.
I'm in NE Kansas now. I'm guessing puts me in range of significant impact. If that quake pushes the water back in the Mississippi like last time, is likely to be a cascading effect up the Missouri River, the then Kansas River. I only live a couple of miles from the junction of the Kansas River and the Big Blue River.
