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 risk for commuicable disease transmission after disasters is associated primarily with the size and characteristics of the population displaced, specifically the proximity of safe water adn functioning latrines, the nutritional status of the displaced population, the level of immunuty to vaccine-preventable diseases..., and the access to healthcare services"

"...natural disasters (regardless of type) that do not result in population displacement are rarely associated with outbreaks"

"When death is directly due to the natural disaster, human remains do not pose a rise for outbreaks"

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
