Dutchsinse | 6/15/2012 --Saint Louis Missouri Shakes -- Charts show it -- USGS doesn't report it

Firsthand report from South St. Louis Missouri -- at approx 1230pm CDT , June 15, 2012 (today) -- minor rumbling , rattle of windows, and a few glass items rattled on the table tops.
St. Louis seismic charts show the event, However USGS has chosen not to report this earthquake on its map/service for some reason....... again.. the chart shows it... USGS skipped it??!! Is not reporting it?!
Here is the chart:
