new madrid seismic zone

In its first One-Year Seismic Hazard Forecast, the United States Geological Survey indicates an increased short-term risk for natural earthquakes in the New Madrid seismic zone for 2016. The forecast is also the first to show potential ground-shaking hazards from both human-induced and natural earthquakes.

Missouri’s bootheel felt a magnitude 4.0 earthquake last night. The United States Geological Survey reported the initial shock hit around 10:51 PM about 2 miles south of Steele in the far southeast corner of the state. There have been no reports of damage.

2015 is the bicentennial of the Federal Government’s first disaster relief act, passed in the wake of the New Madrid Earthquakes of 1811 and 1812. The aid, however, came nearly three years after the magnitude 7 and above quakes occurred.

Geologists with Indiana University and several other Midwestern schools have identified widespread seismic activity along an “underappreciated” seismic zone in southeast Missouri and southern Illinois. 

The seismic zone is named after a small Missouri town --- but it’s not New Madrid.

A select group of Murray firefighters will undergo an elite training course next month to help rescue professionals respond to damaged buildings and disaster scenarios.

Murray is undergoing city-wide disaster drills tomorrow to examine how local agencies respond to a significant earthquake event.

Western Kentucky lies just east of the New Madrid Seismic Zone which has produced over 4,000 recorded earthquakes. The fault is speculated to produce another large event sometime in the future. 


USGS Scientists Bill Ellsworth and Oliver Boyd join Kate Lochte on Sounds Good to speak about regional work involving earthquakes and the New Madrid Fault Line. Ellsworth’s research says injection-induced earthquakes are more prevalent than fracking induced earthquakes. Boyd explains the Missouri Bootheel aeromagnetic survey going on now, tracking seismic activity on certain areas of the fault and furthering research to learn about the faults and to better predict future earthquakes.

  The U.S. Geological Survey is conducting low-level flights across sections of the New Madrid earthquake seismic zone. The USGS will begin conducting the flights tomorrow over a 1,400-square-mile area across southeastern Missouri, northeastern Arkansas and western Tennessee.
