I remember a few years ago, this was the talk for a while -- the gloom and doom -- catastrophe for the surrounding areas
Talk about how the Mississippi River would flood all the lower states if a SHTF scenario were to happen due to a major EQ
Then it kinda went away especially after Dec.21, 2012 came and went
Well, here it is again in the news.....
Study: New Madrid fault zone alive and active
LOS ANGELES (AP) — The New Madrid fault zone in the nation's midsection is active and could spawn future large earthquakes, scientists
It's "not dead yet," said U.S. Geological Survey seismologist Susan Hough, who was part of the study published online by the journal Science.
Researchers have long debated just how much of a hazard New Madrid (MAD'-rihd) poses. The zone stretches 150 miles, crossing parts of Arkansas,
Illinois, Indiana, Kentucky, Mississippi, Missouri and Tennessee.
The last major Earthquakes in that area registered about a 7.7 magnitude that spawned powerful jolts that rattled the central Mississippi Valley back
The New Madrid is less understood since it's in the middle of the continent, far from plate boundaries, where as the San Andreas fault occurs along
boundaries of shifting tectonic plates
At first they thought that the New Madrid fault might be going dormant based on GPS readings that showed little strain accumulation at the surface
However, the latest study suggests otherwise. Hough and USGS geophysicist Morgan Page in Pasadena, Calif., analyzed past quakes in the New Madrid
region and used computer modeling to determine that the continuing tremors are not related to the big quakes two centuries ago.
"Our new results tell us that something is going on there, and therefore a repeat of the 1811-1812 sequence is possible," Hough said.
*But have no fear*
The USGS estimates there's only a 7 to 10 percent chance of that happening in the next 50 years or so
The U.S. Geological Survey considers the earthquake hazard level for this area to be high. However, scientists have struggled to understand
exactly what’s going on beneath the surface and what it might mean for the future.
