When Was the New Madrid Fault Earthquake?

By Robert Palmer

The New Madrid Fault earthquake is one of the most significant natural disasters in American history. It was a series of four earthquakes that struck the central United States from December 1811 to February 1812. The earthquakes were so powerful that they were felt as far away as New York City, Boston, and even Montreal.

What Caused the New Madrid Fault Earthquake?

The New Madrid Fault earthquake occurred due to the movement of tectonic plates. The North American plate and the Eurasian plate grind against each other, causing immense pressure to build up. When this pressure becomes too great, it is released in the form of an earthquake.

When Did it Happen?

The first earthquake occurred on December 16, 1811, with a magnitude of 7.5 on the Richter scale. This was followed by two more earthquakes on January 23 and February 7, both with magnitudes over 7. The fourth and final earthquake occurred on February 12, with a magnitude estimated to be between 7.6 and 8.0.

How Did it Affect the Area?

The impact of the New Madrid Fault earthquake was devastating to the central United States. It caused widespread damage across five states: Missouri, Arkansas, Tennessee, Kentucky, and Illinois.

The ground shook violently for several minutes during each quake, causing trees to fall and rivers to change direction. Towns were destroyed or severely damaged by landslides and collapsing buildings.

The Aftermath

In total, there were over 2000 recorded aftershocks following the New Madrid Fault earthquakes. Many people died from falling debris or drowning in newly formed lakes created by landslides blocking rivers.

The economic impact was also significant as many farmers lost their crops due to changes in river flow caused by landslides.

Conclusion

The New Madrid Fault earthquake was a defining moment in American history. Its impact on the central United States was felt for years to come, and it remains one of the most significant earthquakes to have ever occurred in the country.

By understanding what caused this disaster, we can work towards better preparation and prevention of future earthquakes.
