The solid straight line in the middle of the New Madrid seismic zone is the surface projection of the modeled fault, which ruptures in the simulation. The colors are keyed to the peak intensity of ground velocity at the surface.
Mar 4, 2022 · The New Madrid Fault Line, which produced three massive quakes in 1811-1812, still poses a threat of a major earthquake in the next 50 years. Experts warn of the potential damage, disruption and lack of preparedness in the region, where 45 million people live.
The period passed with no major earthquake activity in New Madrid or along the 120-mile (190 km) fault line. Uncertainty over recurrence potential. The lack of apparent land movement along the New Madrid fault system has long puzzled scientists.
The New Madrid seismic zone has a history of major earthquakes over the past 4,500 years and is still seismically active. The USGS estimates the chance of having another 1811-12 magnitude earthquake in the next 50 years is about 7 to 10 percent.
New Madrid Seismic Zone Catastrophic Planning Project. According to current scientific understanding, the New Madrid Seismic Zone is capable of producing damaging earthquakes at any time. The earthquakes of 1811-12 were estimated to be between a M7.0-8.0 and occurred in an area that was sparsely populated. Were these earthquakes to occur today ...
