I thought that because of the Sea-Flor spreading, and the Subduction near the continental land masses that earthquakes would only be near the coastal regions...wth!

I'm in Peoria and the overly dramatic hens in the office didn't notice/say anything.

I'm in Waukegan, about 5 minutes ago I was in one of the restrooms here flinging mud. I had 'Double Fiber' whole wheat bread and a bowl of brussel sprouts last night. It's possible you felt one of my gassy emissons.

there have been minor earthquakes in NW Ohio even. Anywhere there is any type of fault line, quakes are possible. The major continental plates grinding against oceanic plates are the cause of major quakes. But little quakes can be felt in a wide range of places. I can't really explain why there are minor fault lines in random places on a major continental plate, but there are. But 4+ quakes could definitely be said to be rare on such minor faults (isn't that what the first quake in Illinois was? Like a 4.5?).

yes, it's reported on the USGS website, here's the link:

http://earthquake.usgs.gov/eqc.../Quakes/us2008rgbr.php

I knew I felt something! And that is the eaxct time too.

I looked at that site for an hour and it was never listed, so I gave up. I wonder what took them so long to list it?

quakes aren't reported immediately iirc because they need to poll all reporting stations in the region and do some maths to determine the epicenter.
