I grew up learning about the New Madrid Seismic Zone and the major earthquakes of 1811 and 1812. The earthquakes led to mass migrations outside the area, modified the borders of Missouri, caused the Mississippi River to flow backwards, and was felt as far away as Boston.
The USGS has made a neat poster of twenty "cool" facts about the zone. One can view the PDF version online or click on the graphic above to read it. For those interested in historical and physical geography this is an interesting read!

I check the USGS site every day to see the activity along the fault. The witness accounts of the 1811-12 quakes are compelling reading, and I wish they were emphasized more in school programs. Thanks for the notice about the poster--it's packed with interesting info!
