The New Madrid fault zone (NMFZ) is a long-established weakness in the Earth’s crust in the central and eastern US where earthquakes have occurred for hundreds of millions of years. In 1811-1812, three large earthquakes (up to magnitude 7.5) caused severe damage to the area. 1 At the time, the region was sparsely populated; today it is a ...
Dec 5, 2015 · In the 25 years since Browning’s December 1990 prediction, a large earthquake hasn’t occurred in the New Madrid.

Dec 3, 2020 · A map of earthquakes recorded in the New Madrid Seismic Zone from June 1974 to July 2011. In a 1990 interview, Iben Browning, a self-proclaimed climatologist, predicted that the St. Louis area was in for a major earthquake along the New Madrid Seismic Zone. He forecast that it would happen right around Dec. 3, 1990, sparking a media frenzy in ...
Recent data, however, are coming together to give new insight. Taken together, the new data suggest that the New Madrid seismic zone may be shutting down after the recent cluster of large earthquakes in the past 1000 years. If so, it will be a very long time until the large earthquakes of 1811-12 recur. This view comes from combining four key ...
Dec 3, 2023 · The New Madrid fault has had lesser shakes since 1811 and makes minor ones every few months. ... predicted a 50-50 chance of one on Dec. 2-3. Widely scoffed, the prediction drew many reporters to ...
