Wow! Everybody wants to get in on the action! Much like the hurricane, I've noted for some time that the New Madrid zone is on the move. This has to happen if we want to stick to the schedules that the paleoseismic evidence indicates. The existing fault zone may take centuries to get out of the stress shadow, so the seismicity has to move to areas of higher stress. Even without injection, the Mississippi Valley has plenty of water for earthquakes.
I'm sure they felt this pretty good, since the whole place is one big jelly bowl. We'll wait for the news reports.
Update: Intensity VI, which is strong shaking but light damage. Somewhere around 10 cm/s.
