Is the New Madrid Fault Moving?

By Michael Ferguson

The New Madrid Fault is a well-known seismic zone located in the central United States. It is comprised of a series of faults that run through several states including Arkansas, Missouri, Tennessee, and Kentucky.

The fault system was responsible for some of the largest earthquakes ever recorded in North America in 1811-1812. Since then, people have been keeping an eye on the fault to understand its movements and predict any future earthquakes.

Currently, there is no evidence to suggest that the New Madrid Fault is moving at an unusual rate. However, it is important to note that earthquakes can occur at any time without warning. Scientists monitor seismic activity in the region using various methods including seismographs and GPS technology.

According to recent data from the United States Geological Survey (USGS), there have been no significant quakes along the New Madrid Fault in recent years. The last major earthquake occurred on February 7, 1812, with a magnitude estimated between 7.5-8 on the Richter scale. Since then, there have been smaller quakes but nothing comparable in magnitude.

Despite the lack of recent seismic activity, it’s important to be prepared for earthquakes in areas surrounding the New Madrid Fault. The USGS suggests having an emergency plan and kit ready in case of a disaster.

What Causes Earthquakes?

Earthquakes are caused by tectonic plates shifting beneath the Earth’s surface. Tectonic plates are large slabs of rock that make up the planet’s crust and are constantly moving due to heat from within the Earth’s core. When these plates shift or collide with each other, energy builds up and causes seismic waves which result in an earthquake.

The New Madrid Fault is located at a point where three tectonic plates converge – the North American Plate, Caribbean Plate and Cocos Plate – making it a particularly active area for seismic activity.

Preparing for an Earthquake

Living in an earthquake-prone area means that it’s important to be prepared for a potential disaster. Here are some tips to help you prepare for an earthquake:

  • Create an emergency plan with your family and discuss what to do in case of an earthquake.
  • Prepare an emergency kit which includes essentials such as food, water, first aid supplies, and a flashlight.
  • Secure heavy furniture and appliances to prevent them from falling during an earthquake.
  • Know the evacuation routes in your area and practice evacuation drills with your family.

Conclusion

In conclusion, while there is no evidence to suggest that the New Madrid Fault is moving at an unusual rate currently, it’s important to always be prepared for a potential earthquake. The USGS monitors seismic activity in the region closely and provides valuable information about potential hazards. By being informed and prepared, you can help keep yourself and your family safe in case of a disaster.
