How Long Did the New Madrid Earthquake Last?

By Robert Palmer

On December 16, 1811, the New Madrid earthquake, also known as the Mississippi Valley earthquake, struck in the central United States. This was one of the largest earthquakes to ever hit North America and caused a significant amount of damage throughout the region. But just how long did this devastating earthquake last?

According to historical records, the New Madrid earthquake lasted for several days and was felt across a vast area. The initial tremors began on December 16th, and were followed by a series of aftershocks that continued for months afterward.

The intensity of the shaking varied throughout the region, with some areas experiencing more severe shaking than others. Reports from eyewitnesses describe buildings collapsing, trees uprooting, and even entire islands in the Mississippi River disappearing.

Scientists today estimate that the New Madrid earthquake had a magnitude of between 7.5 and 8.0 on the Richter scale, making it one of the most significant seismic events in North American history.

Despite its size and scope, however, there were relatively few fatalities associated with this event. This is partly due to the fact that much of the region was sparsely populated at this time. Additionally, many people who lived in rural areas were able to take cover outside or in structures that were more resistant to collapse than those found in urban centers.

In conclusion, while there is no single answer to how long did the New Madrid earthquake last as it continued for months afterward with aftershocks but its initial tremors began on December 16th which marked one of America’s most devastating earthquakes till date. Even though there were not many fatalities associated with this event due to sparse population at that time but many people lost their homes and other properties due to severe shaking caused by this catastrophic event.
