I think I felt this.... wondered what it was... like a small EQ in LA.... thought it was the wind... got up, but didn't see much tree limb movement outside in the streetlamp light... thought eq? here? Hmmm.... so now I guess it was... though downstate quite a ways... was faint upstate here in Illinois, surprised I felt it... actually, didn't feel it so much as noticed the vibration in the house upstairs... closet door, things on shelf.... standing still, I felt nothing. Oh well, there is a faultline that runs through there... maybe it connects with the New Madrid faultline?... Nice to know we aren't left out of all the 'action' here in the heartland.
