The New Madrid Seismic Zone is made up of reactivated faults that formed when North America began to split or rift apart during the breakup of the supercontinent Rodinia in the Neoproterozoic Era (about 750 million years ago).

The Mid-Atlantic Ridge or the Marianas Trench.
No because the New Madrid quakes occurred far inland, so therefore no tsunami was generated by the plate tectonics under a large body of water as is the mechanism for most earthquake-generated tsunamis. However, the New Madrid fault earthquake did cause the Mississippi river to flow backwards.
Indiana and a number of neighboring states experience earthquakes, which in modern times have been small and nondestructive. It is unusual to have a major fault in the middle of a continent, but that does exist in this region.Southern Indiana is close to the New Madrid fault. New Madrid, now in Missouri, was the location of the New Madrid earthquakes, 1811-1812, which historical accounts suggest were the largest ever recorded in the eastern US and possibly the largest in North America. The fault is now well mapped and the active area includes several neighboring states and much of Indiana.

The New Madrid Fault System has also been called the New Madrid Fault Line and also the New Madrid Seismic Zone. It is an abundant source of intraplate earthquakes in the southern and Midwestern states.

The New Madrid Fault Line is a seismic zone that extends through several states, including Mississippi.
The largest major city closest to the New Madrid Fault is Memphis, Tennessee. It is located approximately 100 miles southwest of the fault line.
The New Madrid Seismic zone is in the middle of the North American Plate.
