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.

The author contacted both the NRC and the nonprofit Disaster Accountability Project for statements and information on the safety of the plant and if emergency plans were in place. The NRC gave statements and information on their discussions with the Disaster Accountability Project, and the nonprofit described their process of sending freedom-of-information requests to 20 jurisdictions in NY, NJ, and CT located up to 50 miles from Indian Point, in order to determine if they had emergency plans related to the power plant and what they might be

1: Crowding is shown to be common in displaced populations, and local overpopulation/crowding often facillitates the transmittion of disease

2: Natural disasters that do not cause a displacement of a population are rarely associated with disease outbreaks

3: There is little or no evidence that dead bodies, as some believe, pose a epidemic risk for a population of survivors after a disaster has struck

"The federal Nuclear Regulatory Commission requires communities located within 10 miles of nuclear power plants to develop emergency plans. In New York, the four counties within 10 miles of Indian Point—Westchester, Rockland, Putnam and Orange—have taken such measures. But the Disaster Accountability Project, a nonprofit organization that monitors disaster response programs and the author of the report, cited the commission’s response to the 2011 nuclear accident in Fukushima, Japan, in which it recommended that U.S. citizens within 50 miles evacuate."

"NRC spokesman Neil Sheehan said the Fukushima site isn’t comparable to any in the U.S. 'Quite frankly, we don’t have any nuclear plant complexes where you have so many reactors packed so closely together.'"

"Those communities are exempt from the NRC’s emergency planning zones, so most haven’t developed such plans or conducted studies. According to several of them, they couldn’t without help from the federal government."

I did further research into what the Disaster Accountability Project is and what they are trying to accomplish. I also looked into the NRC and how they are focused on safety of nuclear power in the US, and what some of their differences are with the DAP. Finally, I looked up the Indian Point Energy Center, in order to find out the size and scope of the plant and some of the concerns people have about nuclear power in their area
