Today’s Earthquake Fact
Important surface deformation features left as a result of the 1811-1812 earthquakes are the Reelfoot fault scarp, a large sand blow liquefaction field, and Big Lake and St. Francis sunklands in northeast Arkansas. The scarp is an uplift of the surface above the fault. The New Madrid earthquakes littered the region with sand blows. Many of these features can be seen today as white splotches in agricultural fields.
