Residents near the New Madrid Fault Line woke up to seismic activity on Monday as seven minor earthquakes shook the region, according to officials from the Evansville/Vanderburgh County Emergency Management Agency in Indiana. The quakes, ranging in magnitude from 1.8 to 3.0, were recorded in southern Missouri and northern Tennessee, areas historically known for significant seismic activity.
The U.S. Geological Survey (USGS) detailed the locations and times of the earthquakes:
December 9, 2024
- Marston, MO: Magnitude 2.2, 7:30 a.m.
- Howardville, MO: Magnitude 1.9, 6:25 a.m.
- Ridgely, TN: Magnitude 1.8, 5:31 a.m.
- Howardville, MO: Magnitude 3.0, 4:27 a.m.
- Howardville, MO: Magnitude 2.1, 12:27 a.m.
- Matthews, MO: Magnitude 2.2, 12:08 a.m.
- Hayward, MO: Magnitude 2.0, 12:00 a.m.
The epicenters were concentrated near the towns of Marston, Missouri, and Ridgely, Tennessee. Missouri’s State Emergency Management Agency (SEMA) is monitoring the activity and encourages residents to stay informed about earthquake risks and safety measures.
Historical Context of the New Madrid Fault
The New Madrid Fault Line is infamous for its seismic history. Between 1811 and 1812, the fault generated a series of powerful earthquakes estimated to be between magnitude 7 and 8. These massive quakes devastated settlements along the Mississippi River and were felt as far away as Hartford, Connecticut, and Charleston, South Carolina. The event reshaped the region’s geography, including temporarily reversing the flow of the Mississippi River.
While Monday’s quakes were much smaller, they serve as a reminder of the fault line’s potential for future activity.
Be Prepared: Earthquake Safety Tips
The USGS and emergency management officials urge residents in earthquake-prone areas to take precautions. Key safety tips include:
- Have an Emergency Kit: Include water, non-perishable food, flashlights, and first aid supplies.
- Secure Heavy Items: Anchor furniture and appliances to walls to prevent them from tipping over.
- Drop, Cover, and Hold On: In the event of an earthquake, get under sturdy furniture and hold on until shaking stops.
- Create a Communication Plan: Ensure your family knows how to contact each other in case of an emergency.
