LLI: A Whole Lot of Shakin’ Going On…and It’s Our Fault

In December 1811 and January/February 1812, the central and eastern parts of our country were really rockin’. It is estimated that there were more than 2,000 earthquakes during this time caused by the New Madrid Seismic Zone (NMSZ), located near the southeastern Missouri/southern Illinois border. There were three major quakes of 7.0 and larger during this time. The New Madrid Fault extends more than 120 miles, and it is today a major concern to the US Geological Survey (USGS). Its location on ancient bedrock could produce an earthquake of the same magnitude, shaking an area approximately 20 times greater than quakes in California.  The USGS is very concerned because we are not ready. Join us as we continue to discuss the geology of North America, including the failed Midcontinent Rift System.
