Formation of lakes and ponds due to sinking of the land, most notably Reelfoot Lake in Tennessee
Sinking of large tracts of forest, so much so that some of the tree tops were visible at eye-level
Courses of rivers and streams changed due to changing topography from the uplifts and faulting during the quakes
Flooding
Fissures
Extrusions
Creation of domes; Blytheville Dome near the Missouri line with 7-10 mile radius and Little River Dome west of St. Francis River were both created from the New Madrid quakes
Total destruction of Little Prairie, 30 miles south of New Madrid
Water spouts
Landslides along the bluffs resulting in the destruction of livable land
Landslides into the Mississippi river which caused huge waves that overwhelmed boats and washed others on shore.
Sand bars gave way and islands disappeared
Waterfalls appeared where portions of the riverbed were uplifted
Structures were damaged in Louisville, KY, 400 miles away from the epicenter
