A magnitude 7.6 earthquake in the NMSZ is expected to cause major damage near the fault system in the Missouri Bootheel, northeast Arkansas and western Kentucky and Tennessee.

Earthquakes that occur in the New Madrid seismic zone potentially threaten parts of seven American states: Illinois, Missouri, Arkansas, Kentucky, Tennessee, and to a lesser extent Mississippi and Indiana.

The Center for Earthquake Research and Information and others maintain websites that depict locations of recent earthquakes in the New Madrid Seismic Zone, along with related information.

The New Madrid Seismic Zone (NMSZ) extends 120 miles south from Charleston, Missouri, following Interstate 55 to near Marked Tree, Arkansas. The NMSZ consists of a series of large, ancient faults that are buried beneath thick, soft sediments. These faults cross five state lines, the Mississippi River in three places and the Ohio River in two ...

In the New Madrid region, the earthquakes dramatically affected the landscape. They caused bank failures along the Mississippi River, landslides along Chickasaw Bluffs in Kentucky and Tennessee, and uplift and subsidence of large tracts of land in the Mississippi River floodplain.

Sep 3, 2016 · The New Madrid fault impacts Missouri, Illinois, Indiana, Arkansas, Kentucky, Tennessee, Oklahoma and Mississippi. This guide also contains information on other Missouri faults/seismic zones.

The New Madrid Fault extends approximately 120 miles southward from the area of Charleston, Missouri, and Cairo, Illinois, through Mew Madrid and Caruthersville, following Interstate 55 to Blytheville, then to Marked Tree Arkansas. It crosses 5 state lines and cuts across the Mississippi River in 3 places and the Ohio River in 2 places.

Sep 27, 2022 · The Quaternary Fault and Fold Database of the United States database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the …

Earthquake hazards involve more than just strong ground shaking from passing seismic waves. The 1811-12 earthquakes caused many types of ground failures including landslides along the Mississippi River bluffs from Mississippi to Kentucky.

The series of earthquakes destroyed several settlements, dramatically affected the landscape and even altered the flow of the Mississippi River. People on the East Coast of the United States felt shaking, and church bells reportedly rang as far away as South Carolina.
