What Cities Would Be Affected by the New Madrid Fault?

By Alice Nichols

The New Madrid Fault is a seismic zone located in the central United States which extends from northeastern Arkansas, through Missouri, western Tennessee, western Kentucky, and southern Illinois. This fault has been responsible for some of the most significant earthquakes in American history. The largest earthquake known to have occurred in this region was in 1811-1812 and is estimated to have had a magnitude of 7.5-7.9.

What cities would be affected by the New Madrid Fault?

The New Madrid Fault is unique because it is not located near any tectonic plate boundaries, unlike most other faults. As a result, it is difficult to predict when the next earthquake will occur along this fault line. However, if an earthquake were to happen along the New Madrid Fault today, it could potentially affect several major cities in the midwestern United States.

St. Louis, Missouri

One of the most significant cities that could be affected by an earthquake on the New Madrid Fault is St. Louis, Missouri. St. Louis sits right on top of the fault line and has a population of over 300,000 people.

Memphis, Tennessee

Another city that could be significantly impacted by an earthquake on this fault line is Memphis, Tennessee. Memphis has a population of over 650,000 people and sits just west of the fault line.

Nashville, Tennessee

Nashville is another city that could be impacted by an earthquake on the New Madrid Fault. Although it sits east of the fault line and may not experience as severe shaking as other areas closer to it may feel tremors and aftershocks if a significant earthquake were to occur.

Little Rock, Arkansas

Little Rock also falls within close proximity to the New Madrid Fault and could experience significant damage from an earthquake along this fault line. The city has a population of over 197,000 people.

Other areas

Other areas that could be impacted by an earthquake on the New Madrid Fault include parts of Missouri, Arkansas, Kentucky, and Illinois. These areas are mostly rural but could still experience significant damage from a seismic event.

  • Conclusion:

In conclusion, the New Madrid Fault is a significant seismic zone located in the central United States that could potentially impact several major cities. Although it is difficult to predict when the next earthquake will occur along this fault line, it is important for those living in or near these areas to be prepared and have an emergency plan in place.
