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.

Schmid works to analyze the course of events that occured at Fukushima as well as outline what a nuclear emergency response group needs in order to be successful. She specifically addresses the knowledge and expertise that would be necessary. She also highlights the lack of international authority and the implications that holds.

This study would be useful because it shows the prevalence of overdiagnosis. It shows that while the nuclear disaster did cause an increase in the observed thyroid cancers, this was well above the expected number of cases. While they did not present the dangerous implications of overdiagnosis, this is something that could be researched further. It can be considered a good thing that these cases were found through the Program put in place, but can also cause harm if unnecessary radiation was administered.
