I'm in Osage County (which we call "The OC") on the north side of Keystone Lake at what would be about 76th St North as it relates to Tulsa and line up with the outskirts of Mannford which is to the south. We're in a valley that leads to Keystone Lake on a very sold bedrock shelf and it shook hard for probably 90 seconds or more.
Kinda felt it here in Newkirk.
Had just gone to bed and heard what I thought was a hell of a wind gust shaking the big window by the bed. Then the wifey said that the glass door of the cabinet was shaking too. I then realized we had a little quake.
