The New Madrid Fault is a seismic zone located in the central United States. It is responsible for some of the most significant earthquakes in American history.
The fault system runs from Illinois to Arkansas and is named after the town of New Madrid, Missouri, where a series of powerful earthquakes occurred in 1811 and 1812. Since then, the area has experienced occasional earthquakes, but when was the last time the New Madrid Fault had an earthquake?
Recent Activity
The last significant earthquake in the New Madrid Fault zone occurred on February 21, 2020. The quake measured 3.7 on the Richter Scale and was centered near Ridgely, Tennessee. While this might not seem like a particularly strong earthquake, it is rare for any seismic activity to occur in this region.
The Historical Record
When we look at the historical record, we see that earthquakes are infrequent but not uncommon in this region. From December 16th to March 15th of 1811 and again on January 23rd of 1812, four major earthquakes shook the New Madrid region causing widespread destruction.
Powerful Quakes
The first quake was so powerful that it caused waterfalls on the Mississippi River to flow upstream temporarily. These quakes were felt as far away as Washington D.C., Boston, and even Montreal.
Recent Quakes
Since then, there have been several moderate-sized quakes over time with varying magnitudes.
- In November 1968 – A magnitude-5.4 earthquake struck near Daleville, Illinois.
- In October-November of 1985 – three quakes with magnitudes between 4-5 shook southeastern Missouri.
- In June-July of 1986 – two more magnitude-4 quakes occurred near Charleston, Missouri.
Conclusion
In conclusion, while the New Madrid Fault doesn’t experience frequent seismic activity, it is still an active fault line that could produce a significant earthquake at any time. The last significant earthquake in this region occurred in February 2020, and it is impossible to predict when the next one will occur. It is essential to be prepared for such an event by having an emergency kit and a plan in place.
