I live in north central OK.
OK has been having a lot of earthquakes recently, i know... but we rarely feel them here AT ALL where I live.
Today we felt a very significant one that lasted almost half a minute. We have only felt 2-3 in the last few years. This one today was the second strongest we ever felt.
Connection? who knows... just sayin.
This is the first one I have ever felt and there have been quite a few, I know. I am just West of OKC.
I just had to assume it was a quake.
