Seismic St. Louis

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.

Emergency responders were not the main focus of the film but were portrayed as having to deal with difficult situations that they had little real control over, mostly because the state was portrayed as trying to do the right thing but making things worse. The consequences of the government fell on the emergency workers. The doctors and responders had to risk personal safety and had to deal with people not trusting them and ignoring their requests.

The purpose of the article is to underscore the difficulties and importance of post-disaster research investigation into why exactly the structural collapse of the towers happened. Dr. Knowles does this by looking into the cause, investigation, and aftermath of several historical building catastrophes in the US.   These cases have reveal how politics, public, and private entities contributed to the disasters and what tends to happen in the aftermath. In the case of the World Trade Center, Dr. Knowles identifies the main reasons for the structures failing and how other sky scrapers are susceptible to the same attack.
