By Alice Nichols

The New Madrid Fault Line is one of the most active earthquake zones in the United States. It is located in the central part of the country and stretches for over 150 miles from southern Illinois to northeastern Arkansas. Here is a list of states that the New Madrid Fault Line runs through.

Illinois

The New Madrid Fault Line runs through the southern part of Illinois, which includes cities like Cairo, Metropolis, and Shawneetown. The region has a history of seismic activity, with several earthquakes recorded since 1800.

The most significant earthquake to hit Illinois was in 1811 when a magnitude 7.8 earthquake shook the area.

Missouri

The majority of the New Madrid Fault Line runs through Missouri, including cities like Charleston, Sikeston, and New Madrid (which gave the fault line its name). The region experiences frequent minor earthquakes that are often felt by residents.

The most significant earthquake to hit Missouri was also in 1811 when a magnitude 7.8 earthquake caused significant damage to homes and buildings.

Arkansas

The eastern part of Arkansas is home to a portion of the New Madrid Fault Line. Cities like Blytheville, Jonesboro, and West Memphis are located near this section of the fault line.

The region experiences frequent minor earthquakes that are often felt by residents.

Kentucky

A small portion of western Kentucky is situated on top of the New Madrid Fault Line. Cities like Paducah and Mayfield are located near this section of the fault line.

While seismic activity in Kentucky is not as frequent as other states along the fault line, earthquakes can still occur.

Tennessee

The western part of Tennessee is located near the New Madrid Fault Line. Cities like Memphis, Jackson, and Dyersburg are situated in this region.

The area experiences frequent minor earthquakes that are often felt by residents. The most significant earthquake to hit Tennessee was in 1811 when a magnitude 7.

Conclusion

The New Madrid Fault Line runs through five states in the central part of the United States: Illinois, Missouri, Arkansas, Kentucky, and Tennessee. While seismic activity is not constant in these areas, residents should be aware of the potential for earthquakes and take necessary precautions to ensure their safety.
