It shook enough for me!

In the past year we have had a lot of earth quakes in central Oklahoma… they are all deep and not horrible strong but enough that we can feel it.  I unfortunately have not felt any of them until last night… I felt that one… thought my chair, I was at the radio operating position, slid off something? http://newsok.com/4.4-magnitude-earthquake-shakes-central-oklahoma/article/3931999.  They did lower it to a 4.1 but it rocked my chair… I guess we will have new mountains or a valcano pop up soon east of OKC?  ha!
