Recent earthquakes in Missouri
Missouri's earthquake hazard comes almost entirely from the New Madrid Seismic Zone in the state's southeast, a major intraplate fault system deep within the North American Plate. In the winter of 1811-1812, this zone produced a sequence of earthquakes estimated at magnitude 7 to 7.5, among the largest in the eastern United States. It remains active today with frequent small earthquakes. In the past 24 hours, Missouri has recorded no earthquakes above the reporting threshold.
Counts include M2.5+ events — the smallest size USGS reports consistently worldwide.
Frequently asked questions
Why does Missouri have earthquakes?
Southeastern Missouri lies over the New Madrid Seismic Zone, an ancient buried rift within the interior of the North American Plate. Faults there remain under stress and produce frequent small earthquakes and, rarely, very large ones.
What were the 1811-1812 New Madrid earthquakes?
Over the winter of 1811-1812, a series of powerful earthquakes, estimated between magnitude 7 and 7.5, struck the New Madrid zone. They were felt across much of the eastern United States and reportedly altered the course of the Mississippi River.
Could a big New Madrid earthquake happen again?
Yes. The New Madrid Seismic Zone remains active, and scientists estimate a meaningful probability of a magnitude 6 or greater earthquake in the coming decades. Because eastern crust transmits shaking efficiently, such an event would affect a wide area.
