The New Madrid Fault is a seismic zone that stretches across several states in the central United States, including Missouri, Arkansas, Tennessee, and Kentucky. This fault line is notorious for its potential to cause earthquakes of significant magnitude, which can be felt across a wide area. The last time the New Madrid Fault experienced a major earthquake was back in 1811-1812.
Background of the New Madrid Fault
The New Madrid Fault was named after the town of New Madrid, Missouri, which was at the epicenter of a series of earthquakes that occurred from December 16, 1811 to February 7, 1812. These earthquakes are considered to be some of the most significant seismic events in American history, with magnitudes estimated to range between 7.5 and 8.0 on the Richter scale.
The Last Major Earthquake
The last major earthquake to occur on the New Madrid Fault happened on February 7th, 1812. The quake had an estimated magnitude of around 7.5-8.0 and caused widespread damage across several states in the central United States. It is believed that this earthquake was felt as far away as Canada and even caused church bells to ring in Boston.
Recent Earthquakes
While there have been smaller earthquakes in recent years along the New Madrid Fault line, none have been nearly as strong as those that occurred back in 1811-1812. In fact, it’s been over two centuries since there has been a major earthquake along this fault.
- In September 2016, there was a small earthquake with a magnitude of just 2.5.
- In May 2019, there was another small earthquake with a magnitude of just 2.8.
- There were also several small earthquakes recorded in March 2020 with magnitudes ranging from 1.3 to 2.4.
Preparing for the Next Big One
While it’s impossible to predict exactly when the next major earthquake will occur along the New Madrid Fault, scientists and emergency management officials are working hard to prepare for such an event. The Federal Emergency Management Agency (FEMA) has identified this fault line as one of the most dangerous in the country, and has urged residents in affected areas to have emergency plans in place.
What You Can Do
If you live in an area that is prone to earthquakes or along the New Madrid Fault line, there are several things that you can do to prepare for a seismic event:
- Make sure that your home or business is structurally sound and up-to-date on building codes.
- Create an emergency plan with your family or coworkers, including a designated meeting spot and evacuation route.
- Stock up on essential supplies, such as food and water, first aid kits, flashlights, and batteries.
- Stay informed about weather conditions and potential disasters by signing up for alerts from your local emergency management agency.
Conclusion
In conclusion, while it’s been over two centuries since the last major earthquake along the New Madrid Fault line, it’s important that residents in affected areas stay prepared. By taking steps now to prepare for a potential seismic event, you can help ensure that you and your loved ones stay safe during any future earthquakes.
