This animation shows the simulated ground motion of the Earth’s surface that could occur in the central U.S. region for a magnitude 7.7 strike-slip earthquake on the southern section of the New Madrid seismic zone. The simulation is based on a detailed geologic model of the central U.S. and is intended to show the general character of the ...

Overview When people think of earthquakes in the United States, they tend to think of the west coast. But earthquakes also happen in the eastern and central U.S. Until 2014, when the dramatic increase in earthquake rates gave Oklahoma the number one ranking in the conterminous U.S., the most seismically active area east of the Rocky Mountains was i...
What is the estimate of the recurrence interval for 1811-1812 type earthquakes? Paleoseismic (geologic) studies conducted over the last 20 years have shown that sequences of earthquakes of comparable size to that in 1811-1812 have occurred at least twice before, in approximately 900 and 1450 AD. This implies a recurrence interval of about 500 years...
Dec 14, 2023 · NPR. Arkansas officials are preparing for a possibly catastrophic earthquake in the New Madrid Seismic Zone. The New Madrid Fault Line sits along the border of Missouri, Tennessee and...
Mar 3, 2022 · But the New Madrid (MAH’-drid) Fault Line centered near the southeast Missouri town of New Madrid produced three magnitude 7.5 to 7.7 earthquakes that rang church bells as far away as South Carolina, caused farmland to sink into swamps and briefly caused the Mississippi River to flow backward. Those quakes happened in late 1811 and early 1812.
