The New Madrid Fault is a fault that runs through several states in the United States, including Missouri, Arkansas, Tennessee, and Kentucky. It is named after the town of New Madrid, Missouri, which was near the epicenter of a series of powerful earthquakes that struck the region in 1811 and 1812.
What is the New Madrid Fault?
The New Madrid Fault is a geological feature that marks a boundary between two tectonic plates: the North American Plate and the Caribbean Plate. The fault is actually a complex network of faults that extends for more than 150 miles (240 kilometers) through the central United States.
The History of the New Madrid Fault
As mentioned earlier, the most significant seismic activity associated with the New Madrid Fault occurred in 1811 and 1812. These earthquakes were some of the most powerful to ever strike North America east of the Rocky Mountains. They were felt as far away as Washington D.C., Boston, and even Montreal.
Since then, there have been smaller earthquakes associated with the New Madrid Fault, but none have been as large or destructive as those in 1811-12. However, scientists warn that another major earthquake could occur at any time.
How Long Is It?
As mentioned earlier, the New Madrid Fault extends for more than 150 miles (240 kilometers). This makes it one of the longest faults in North America.
Other Facts About The New Madrid Fault
– The fault was discovered by French explorer Jean Baptiste Le Moyne de Bienville in 1699. – The name “New Madrid” comes from a Spanish fort built near present-day Tiptonville, Tennessee in 1789.
– Scientists estimate that there is a 25-40% chance of a major earthquake occurring along the New Madrid Fault within the next fifty years. – A major earthquake along this fault could cause significant damage to infrastructure and potentially disrupt the flow of goods and services throughout the central United States.
Conclusion
The New Madrid Fault is a significant geological feature that poses a potential threat to the central United States. While the likelihood of a major earthquake occurring along this fault in any given year is relatively small, it’s important for individuals and communities in the region to be prepared for such an event. By understanding the history and characteristics of the New Madrid Fault, we can better prepare ourselves for potential seismic activity in the future.
