Seismic St. Louis

Emily Sekine

I'm interested in better understanding the ongoing geological processes that shape St. Louis and the Mississippi Valley region. So far, I've been looking into the history of seismicity in the region, focusing on the fascinating but little known history of the New Madrid earthquakes of 1811 and 1812 -- the most devastating earthquakes to have hit the US east of the Rockies. I've also been exploring how St. Louis and surrounding areas are dealing with the possibility of another earthquake occurring in the future. According to one article I read, one of the biggest uncertainties is what would happen to the heavily engineered Mississippi River in the case of another major tremblor. The shaking could break the levees, flooding wide areas along the river and creating cascading effects. The flow of the river might also reverse completely, as occurred during the New Madrid earthquakes.

On these possibilities and the lack of scientific consensus surrounding intraplate seismicity in this zone, see this article in The Atlantic.

On current efforts to create earthquake hazard maps in St. Louis, see this overview on the US Geological Survey site.

For a deeper dive into the history of the New Madrid earthquakes, see this book by historian of science Conevery Bolton Valencius.

This film follows the story of USMC Master Sgt. Jerry Ensminger. After the death of his 9 year old daughter to lukemia, he searched for the cause of his daughters illness, and his persuit led him to discover a Marine Corps cover-up of one of the largest water contamination incidents in U.S. history at North Carolina's Camp Lejeune. The film follows Jerry's investigation and persuit to make the truth known to the public and to force the Marine Corps to be "always faithful" to the thousands of Marines and their families exposed to toxic chemicals at the camp, and at other military bases across the country where similar occurances took place.
