It’s a deadly threat you may have never heard of. The New Madrid seismic zone is a series of faults that once rocked the U.S. It runs under parts of Missouri, Arkansas and Tennessee.
“The seismic risk in the central U.S. has been defined by Homeland Security and FEMA as catastrophic,” said James Wilkinson, the executive director for the Central United States Earthquake Consortium (CUSEC).
“We do live in earthquake country. This is not just a California problem or a West Coast problem. We have earthquakes throughout the Central and Eastern U.S. It’s not going to take a large event 7.0 or bigger to create significant damage and it could still be categorized as catastrophic,” said Wilkinson.
“It’s going to be messy. We’re expecting magnitude 6 to 7 earthquakes occurring in the New Madrid seismic zone. There’s about a 7% to 8% chance one is going to happen in the next 50 years,” said Thomas Pratt, a geophysicist with the United States Geological Survey. Pratt said the Midwest could face ground shaking as severe as the New Madrid earthquakes that spanned three months during 1811 and 1812.
“Those earthquakes were three of the largest earthquakes in the history of the United States, certainly south of Alaska. Shaking was felt throughout the entire Eastern United States, from Boston all the way down to South Carolina,” Pratt said.
In part two of this four part series, find out why the Midwest is so vulnerable to the next big earthquake.
“Oh, it will definitely happen again. There will be larger earthquakes. It’s an active debate how large those earthquakes will be, but there will definitely be larger earthquakes in the future,” said Pratt.
