The state, the one area on that plate that has not shifted yet and the people in that area don't seem to have a clue.  I think there will be serious problems for that reason.  

Looked up info re New Madrid and found this.



Three Main Shocks

December 16, 1811 - Magnitude ~7.7
January 23, 1812 - Magnitude ~ 7.5
February 7, 1812 - Magnitude ~ 7.7

A Robust Aftershock Sequence

Aftershocks are Earthquakes!
December 16, 1811 - Magnitude ~7.0
Six aftershocks in the first two days in the range of M5.5 to M6.3. Hundreds of quakes felt into 1813.

It's happened before 1811-1812

The geologic record of pre-1811 earthquakes reveals that the New Madrid seismic zone has repeatedly produced sequences of major earthquakes, including several of magnitude 7 to 8, over the past 4,500 years.
