When Was the Last Earthquake on the New Madrid Fault?

By Anna Duncan

The New Madrid Fault is a seismic zone that runs through the central United States, specifically through the states of Missouri, Arkansas, Tennessee, and Kentucky. This particular fault is well-known for its destructive earthquakes that have occurred in the past. The latest earthquake on this fault was in 1812 and it had a magnitude of 7.5 on the Richter scale.

What is the New Madrid Fault?

The New Madrid Fault is a geological formation that runs along the Mississippi River Valley. It was named after a small town in Missouri where it was first identified. The fault zone stretches from Cairo, Illinois to Marked Tree, Arkansas and has been responsible for several major earthquakes throughout history.

The History of Earthquakes on the New Madrid Fault

The New Madrid Fault has been responsible for some of the most powerful earthquakes ever recorded in North America. The most significant series of quakes occurred between December 1811 and February 1812. These earthquakes had magnitudes estimated between 7.5 and 8.0 on the Richter scale, making them some of the most powerful to ever hit North America.

During this period, there were over 2,000 tremors recorded along with several major earthquakes that caused severe damage to towns along the Mississippi River Valley.

The Last Earthquake on the New Madrid Fault

The last significant earthquake on the New Madrid Fault occurred in 1812 as mentioned earlier. Since then, there have been smaller tremors and quakes felt throughout the region but none have been as powerful as those in 1811-12.

Are We Due for Another Earthquake?

There is no way to predict when or if another major earthquake will occur on the New Madrid Fault. However, scientists continue to monitor seismic activity along this fault line closely.

Conclusion

The New Madrid Fault is a significant seismic zone that has been responsible for some of the most powerful earthquakes ever recorded in North America. The last significant earthquake on this fault occurred in 1812, but scientists continue to monitor seismic activity along this fault line closely. It is important to be prepared and have a plan in place for earthquake emergencies, especially for those living near the New Madrid Fault.
