Computer Simulation of a Magnitude 7.7 Earthquake in the New Madrid …
Watch an animation of a magnitude 7.7 strike-slip earthquake on the southern section of the New Madrid seismic zone, based on a detailed geologic model of the central U.S. See how the Reelfoot rift and the Mississippi embayment affect the …
New Madrid Seismic Zone Catastrophic Planning Project - CUSEC
Learn how CUSEC led a multi-state effort to develop and improve earthquake response plans for the region affected by the New Madrid Seismic Zone. The project involved scenario-driven planning, workshops, and a national level exercise to prepare for a M7.7 earthquake.
The New Madrid Seismic Zone | U.S. Geological Survey - USGS.gov
Learn about the history and geology of the New Madrid seismic zone, where the largest earthquakes in the eastern U.S. occurred in 1811-1812. See maps, images, and accounts of the effects of liquefaction, landslides, and river changes.
The Great Midwest Earthquake of 1811 | Smithsonian
Learn about the most powerful earthquakes in the continental U.S. history, which struck Missouri in 1811-12 and could happen again. Discover the ancient faults, the seismic hazard and the...
New Simulations of 1811-1812 New Madrid Earthquakes Show …
Computer simulations of earthquake shaking, replicating the quakes that occurred in 1811-1812 in the New Madrid seismic zone (NMSZ), indicate that future large earthquakes there would produce major, prolonged ground shaking.
Getting ready for the next 'big' quake in Missouri's New Madrid …
Feb 1, 2023 · A study by MU researchers reveals a lack of awareness and knowledge about the earthquake risk in the New Madrid Seismic Zone, where a major quake could cause a catastrophic event. The report...
ongoing background seismicity in the New Madrid region is driven by ongoing strain accrual processes and that, despite low deformation rates, seismic activity in the zone is not decaying with time.
The New Madrid Seismic Zone: Not Dead Yet | Science - AAAS
Jan 23, 2014 · We examined historical and instrumental seismicity in the New Madrid central U.S. region to determine whether present-day seismicity is composed predominantly of aftershocks of the 1811–1812 earthquake sequence.
New Madrid quake analysis rewrites history books
Apr 29, 2010 · A series of earthquakes that hit the North American heartland nearly 200 years ago were considerably smaller than reported in the history books, according to research presented at a meeting this...
currently accepted model of high earthquake risk in New Madrid is an example of “ ‘zombie science’—a theory that’s scientifi cally dead but is still walking around as it fades away.” His alternative model focuses on rare intraplate events that are “episodic, clustered, and migrat-ing,” such that the next New
