USGS is now showing two 7.0 quakes in that region. The second one has a depth of 10 km; however, it has not been reviewed yet.
Just as I posted this, USGS removed the 7.0 at 229.4 km.

I just wanted something on record in case there is an event in TN.
This morning, I noticed all our clouds were lining up in a relatively straight line. I've never seen them like that before and I am a sky watcher. With all the activity in Arkansas, I was wondering if these are earthquake clouds.
I'm kind of new at this, so am I right or is this some other weird weather phenomena that is happening. We did have storms of insane magnitude last night. We got hit by a tornado just a couple of miles west of us (literally).
However, these claims have very little support in the scientific community.
