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.

I looked up how emergency responders deal with mental health, since the method that was described in this article is no longer recommended. I also investigated the types of disaster that people around the world face each year, besides for weather disasters. Furthermore, I looked at a map of the types of disasters across the globe.

The article does not directly address emergency response, however it did address medical stories as being helpful to the public to feel supported and reach out when they realized they had a psychological condition. This is important in society, because if someone can get treated for something, or at least know they have it an take precautions, then they help themselves feel more comfortable and be more successful, they reduce the strain on those around them, and they make it easier for healthcare providers, if there is ever a related issue.
