The New Madrid Fault is a seismic zone that stretches across five states in the southern United States. It is named after the small town of New Madrid, Missouri, where the most powerful earthquakes in U.S. history occurred in 1811-1812. But how did this fault form?
The Formation of the New Madrid Fault
The Earth’s crust is made up of tectonic plates that move around on the planet’s surface. The North American Plate, which includes much of North America and parts of the Atlantic Ocean, is slowly moving towards the west-southwest. However, there are other plates nearby that are moving in different directions.
About 500 million years ago, what is now North America was part of a supercontinent called Rodinia. As Rodinia began to break apart, a rift formed in what is now the central United States. This rift created a large basin that filled with sediment over time.
Continued Rift Activity
Rift activity continued off and on for millions of years until about 200 million years ago when another supercontinent called Pangaea began to form. During this time, magma from deep within the Earth began to rise up and solidify beneath North America.
As more magma rose up, it created a series of cracks and faults in the crust. One such fault was the New Madrid Fault.
Earthquakes Along The Fault
While earthquakes along this fault have been relatively infrequent since written records began in 1811-1812, scientists believe it has been active for at least 500 million years.
The motion along the fault has caused notable uplifts and depressions in some areas along with shaking during earthquake events.
Conclusion
In conclusion, The New Madrid Fault formed as a result of tectonic plate movement as well as volcanic activity beneath North America over millions of years. It is a reminder that while earthquakes in the region may be infrequent, they are a geological reality that should always be taken seriously.
