The New Madrid fault system does not behave as earthquake hazard models assume and may be in the process of shutting down, a new study shows. A team from Purdue and Northwestern universities analyzed the fault motion for eight years using global positioning system measurements and found that it is much less than expected given the 500- to 1,000-year repeat cycle for major earthquakes on that fault. The last large earthquakes in the New Madrid seismic zone were magnitude 7-7.5 events in 1811 and 1812.
Estimating an accurate earthquake threat for the area, which includes parts of Illinois, Indiana, Tennessee, Arkansas and Kentucky, is crucial for the communities potentially affected, said Eric Calais, the Purdue researcher who led the study.
"Our findings suggest the steady-state model of quasi-cyclical earthquakes that works well for faults at the boundaries of tectonic plates, such as the San Andreas fault, does not apply to the New Madrid fault," said Calais, who is a professor of earth and atmospheric sciences. "At plate boundaries, faults move at a rate that is consistent with the rate of earthquakes so that past events are a reliable guide to the future. In continents, this does not work. The past is not necessarily a key to the future, which makes estimating earthquake hazard particularly difficult."
Comment: The wave of propaganda from this so called Climate Congress is astounding. Here are just a few of the stories that the worldwide propaganda machine grabbed onto:
Propaganda: Global temperatures 'will rise 6C this century'
Propaganda: Global warming 'will be worse than expected' warns Stern
Propaganda: Amazon could shrink by 85% due to climate change, scientists say
Propaganda: Sea Levels May Rise Faster Than Expected
Propaganda: Warming Could Cut Population to 1 Billion
Propaganda: Scientists are grim, economists more optimistic about climate change's effects
Propaganda: Make clear dire scenarios to prod climate action
Propaganda: Scientists plan emergency summit on climate change
