The New Madrid Seismic Zone is an area at the northern end of the Mississippi Embayment and extends 120 miles. This is the remnant zone of the Reelfoot Rift during the break up of supercontinent Rodinia. This area is still active today causing multiple earthquakes on a weekly basis, however these earthquakes are quite small. This zone is most familiar with three earthquakes from 1811 - 1812 which were so powerful that they caused the Mississippi to flow backwards. The largest one on February 7, 1812 had a magnitude exceeding 8 on the Richter scale. Activity today includes a . The Reelfoot Rift is named after Reelfoot Lake, which was created by the 1811-1812 earthquakes. The New Madrid Seismic Zone is a prime study area for neotectonics

I don't know when, but there was flooding in Kansas or Kentucky. They reversed the river so that they can prevent the flooding. Actually, the land in Louisiana is not all gone from Global Warming, It's from the reverse of the river.
