Is the New Madrid Fault Still Active?

By Michael Ferguson

The New Madrid Fault is a major seismic zone located in the central and eastern parts of the United States. It is named after the town of New Madrid, Missouri, where the fault was first identified in 1811. The fault is responsible for some of the largest earthquakes ever recorded in North America, including a series of quakes that occurred between December 1811 and February 1812.

What is the New Madrid Fault?

The New Madrid Fault is actually a system of faults that runs from Illinois to Arkansas and from Kentucky to Mississippi. It is located in an area that has historically been considered low-risk for earthquakes, but its seismic activity has increased significantly in recent years.

How active is the New Madrid Fault?

The New Madrid Fault may not be as well-known as some of the other major fault zones around the world, but it still poses a significant threat to those living nearby. The fault remains active to this day, with small earthquakes occurring on a regular basis.

In fact, according to a report by the US Geological Survey (USGS), there were more than 200 small earthquakes detected along the New Madrid seismic zone between 2010 and 2019. While most of these quakes were too small to be felt by humans, they are an indication that the fault remains active and could potentially produce larger earthquakes in the future.

What are the potential risks?

The potential risks associated with an earthquake on the New Madrid Fault are significant. According to some estimates, a major quake on this fault could cause widespread damage across several states and lead to thousands of deaths.

One reason for this is that many buildings in this part of the country are not designed to withstand earthquakes. In addition, there are several large cities located near or on top of the fault zone, including Memphis and St. Louis.

In conclusion

While it is impossible to predict exactly when the next earthquake will occur on the New Madrid Fault, it is clear that the risk remains high. As such, it is important for those living in this region to take steps to prepare for a potential earthquake, including securing their homes and having an emergency plan in place. By taking these precautions, individuals and communities can help minimize the impact of a major earthquake on the New Madrid Fault.
