The New Madrid Seismic Zone (NMSZ) is a region in the central United States that is known for its frequent seismic activity. The NMSZ is located in the Mississippi River Valley and spans across five states: Illinois, Missouri, Arkansas, Kentucky, and Tennessee. Many people wonder what type of plate boundary the NMSZ is and what causes the earthquakes in this region.
What is a Plate Boundary?
Plate boundaries are the areas where two tectonic plates meet. Tectonic plates are massive slabs of rock that make up the Earth’s outer layer or crust. There are three types of plate boundaries: divergent, convergent, and transform.
The Plate Boundary of New Madrid Seismic Zone
The NMSZ does not occur at a typical plate boundary. Instead, it is located within the North American Plate. The earthquake activity in this region is believed to be caused by ancient faults or fractures that formed millions of years ago when the supercontinent Pangaea began to break apart.
History of Earthquakes in New Madrid Seismic Zone
The first recorded earthquake in the NMSZ was in 1811 and had an estimated magnitude of 7.5 on the Richter scale, making it one of the most powerful earthquakes ever recorded in North America. This earthquake caused damage across several states and even created temporary waterfalls on the Mississippi River.
Since then, there have been several other earthquakes in this region with magnitudes ranging from 6.0 to 8.0 on the Richter scale. While seismic activity has decreased significantly since the early 1800s, there is still a risk of future earthquakes in this region.
Conclusion
In conclusion, while most earthquakes occur at plate boundaries where tectonic plates meet and interact with each other, this is not the case with the NMSZ. The NMSZ is located within a tectonic plate and is believed to be caused by ancient faults or fractures in the Earth’s crust. Despite being away from the typical plate boundary, the NMSZ still poses a significant risk of earthquake activity that could have devastating consequences for the region.
