Portageville, Missouri Heliplot/Graphs - Someone please confirm this strong activity?

I am by no means an expert at reading or interpreting graphs, but I do have, I believe, a basic understanding of how seismo readings should and shouldn't look. I check the stations around the U.S. only semi-regularly, but when checking just now, I found the graphs for the town of Portageville, on the New Madrid fault, to be very interesting:

folkworm.ceri.memphis.edu...

Also, if you go back in the 12 hour increments day by day, they are all different and all showing what I believe to be definite seismic activity that is not showing on the USGS site. Because of the booms & smells being reported in the midwest, I figured asking someone to review this data wouldn't hurt.

Additionally, CERI stations and even stations listed on the USGS' ANSS show activity that seems to be centered around southern Illinois & Indiana tonite. It does not seem that there are any big "world quakes" causing these readings, and it is not showing up on graphs outside of the midwest.

Thanks
