Why Is It Called the New Madrid Fault?

By Michael Ferguson

The New Madrid Fault is a well-known seismic zone located in the central United States. It stretches from northeastern Arkansas to northwestern Tennessee and is responsible for some of the most powerful earthquakes in American history.

But have you ever wondered why it’s called the New Madrid Fault? Let’s dive into the history behind this name.

The Origin of the Name

The New Madrid Fault was named after the town of New Madrid, Missouri. This town was established by Spanish explorers in 1789 and was located near the epicenter of a series of powerful earthquakes that occurred in 1811 and 1812.

The Great Earthquakes of 1811-1812

The earthquakes that struck the region in 1811-1812 were some of the most powerful ever recorded in North America. They were so strong that they caused the Mississippi River to briefly flow backward, created new waterfalls, and even caused church bells to ring as far away as Boston.

These earthquakes were felt across a vast area, with reports of shaking as far north as Canada and as far south as Mexico. The damage was severe, with entire towns destroyed and many lives lost.

Scientific Study

After these devastating earthquakes, scientists began to study the area more closely. They discovered that there was a fault line running beneath the region, which they named after the nearby town of New Madrid.

Further research revealed that this fault line is part of a larger system known as the Reelfoot Rift Zone, which extends from Illinois to Alabama. This zone is believed to be an ancient failed rift where tectonic plates tried to separate but ultimately failed.

Conclusion

So there you have it – the New Madrid Fault is named after a town that was located near some of the most powerful earthquakes in American history. Although these earthquakes occurred over two centuries ago, the fault line that caused them is still active today and remains a significant seismic risk for the central United States.

As always, it’s important to be prepared for earthquakes no matter where you live. If you live in an earthquake-prone area, make sure you have an emergency plan in place and know what to do when the shaking starts. Stay safe!
