Of you’re talking new Madrid fault line in southern Illinois then you’re kinda close but a couple hundred-ish miles away even if you’re in Evansville Indiana area. I think the closest volcano is in Washington state to us.
Please don’t make a volcano in southern Indiana, my family in southern Illinois probably won’t enjoy being between a volcano and a major tectonic fault both lol
Edit: just to antagonize any Spaniards reading this, we don’t pronounce muh-drid like it should be, we say mad-rid here in southern Illinois. Fun stuff, idk why we screw it and Cairo both up
