Well, I've heard of cryoseisms, especially up in the Northeast. Never felt one, though.
The cold in Oklahoma (and many other places) is intense, but this occurred a few miles down, so it isn't frost related. Am not too skilled at reading "beachballs," but that looks like it was movement along a normal fault somewhere. (?? local geology??)
Looks like it did some shaking. Did anyone here from that area, especially around OK City or Wichita, feel it?

PS: Thanks for asking, Wes. I've been away for a while but checked back in, figuring you would mention the Persverance Mars landing in the Space forum. Sir, that play-by-play you did, and the high-quality images, are superb!
