The New Madrid Earthquake, the largest earthquake ever recorded in the contiguous United States,

I'm usually defending Wikipedia but in this case they're not up on the latest science.

The most recent peer-reviewed papers on the quakes have reduced their estimated magnitudes significantly. This isn't exciting, hence you haven't seen this mentioned in the mainstream media.

This is the important factor in my book (italic and image) and the damage as well as the costs will be HUGH if the NM ever lets loose...

There are estimates that the (NM) earthquakes were felt strongly over 50,000 square miles, and moderately across nearly one million square miles. The historic San Francisco earthquake of 1906, by comparison, was felt moderately over 60,000 square miles.
