The New Madrid Seismic Zone (NMSZ) is a region in the central United States that has been associated with several large earthquakes in the past. The zone, which stretches from Illinois to Arkansas, was the center of a series of powerful quakes in 1811 and 1812 that caused widespread destruction and were felt throughout much of the eastern United States.
What causes earthquakes?
Earthquakes are caused by the movement of tectonic plates – massive slabs of rock that make up the Earth’s crust. When two plates move against each other, they can create friction and pressure that builds up over time. Eventually, this pressure is released in the form of an earthquake.
Is the NMSZ still active?
The short answer is yes – the NMSZ is still an active seismic zone. While there have not been any major earthquakes in recent years, smaller quakes do occur on a regular basis. According to the US Geological Survey (USGS), there have been over 4,000 recorded earthquakes in the NMSZ since 1974.
Why are scientists concerned about future earthquakes in the region?
One reason scientists are concerned about future earthquakes in the NMSZ is because of its location. Unlike other seismic zones, such as those along the West Coast, which occur at plate boundaries, the NMSZ is located within a tectonic plate. This means that it is more difficult to predict when and where earthquakes will occur.
Another concern is that many of the buildings and infrastructure in the region are not built to withstand large earthquakes. In addition, there are several nuclear power plants located near or within the NMSZ.
What can be done to prepare for future earthquakes?
While it’s impossible to predict when or where an earthquake will occur, there are steps that can be taken to prepare for them. These include:
- Ensuring that buildings and infrastructure are built to withstand earthquakes
- Developing emergency response plans
- Stockpiling emergency supplies, such as food and water
- Regularly conducting earthquake drills and exercises
The bottom line
While the NMSZ is still an active seismic zone, there is no need to panic. It’s important to stay informed about the latest developments and to take steps to prepare for future earthquakes. By working together, we can minimize the damage caused by these natural disasters and keep ourselves and our communities safe.
