Earthquake? Here in Oklahoma?

Holy Crap !!! Hubby and I were just heading to bed tonight.... when this very loud rumble felt like it was right under our house. The windows began to rattle. I thought that a huge water pipe must have broken.  Hubby thought it was a tornado coming down, and told me to get to the safe room.  It probably only lasted about 25-30 seconds, but I am just not in the mood..... Hope you all are well and safe tonight. I may be up a while catching up on my prayers:)
