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.

Examples from history are used to support claims from 9/11, as the author is a historian, and probably following the saying "history repeats itself" to show similarities between disasters and responses.

Newspaper atricles were also cited to show public response.

The study addresses the survivors of Katrina fairly soon after the disaster, at a time when they likely do not have much stability. Many were without homes, may have lost family or friends, neighborhoods were torn apart, schools were destroyed, and money was very thin. It was not an easy time, so focusing on this group at such a stressful time was the goal of the study.

The paper mostly focuses on how the survivors recieve long-term care, since they have severe financial struggles in the aftermath of the disaster. This impacts emergency response since we do need to be funded in some way, and if it is not covered by the healthcare system in the area, then the cost is placed on the individual. If they are in need of immediate care, then this is an issue. They have many health conditions caused by the disaster that could cause a sudden health emergency. If they do not feel they can financially support calling an ambulance, then it places the person's life in jeopardy.

"The contributors write: “Data are important, of course, but numbers sometimes imply an order to what is happening that can be misleading. Stories are better at capturing a different type of ‘big picture'.""

"Four decades later, in 1995, suicidal thoughts brought this anxious man back into the psychiatric system, at age 70. For the first time, he was put on an antidepressant, Zoloft. Six weeks out, both the panic attacks and the depression were gone. He resumed work, entered into a social life and remained well for the next 19 years — until his death."
