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 World Trade Center collapse was a unique disaster for American organizations to deal with, the aftermath and subsequent investigation into the collapse shows a need for a unified system of authority between investigative organizations. The paper shows the development of his system using several other disasters throughout American history.

The argument is supported through a combination of personal stories, historical changes in protocol, and analysis of the reasons why applicants resort to a medical argument for residence permits. The use of personal stories of applicants highlights the inconsistencies in the process largely due to compassionate bias on the part of officials reading the applications, as well as the resources available in different cities. As the protocols were changed the article shows that while some of the inconsistencies were resolved, the process of determining who can and cannot receive medical treatment necessitates personal judgment which inevitably affects the outcome.

The policy addresses the support and funding provided by the federal government to victims of a disaster, including the basic needs such as food, water, and access to health care through responding organizations. This policy focuses on the coordination between responding groups as well as the long term funding and support systems that will be in place to aid survivors with rebuilding.

This organization does not respond to disasters, but rather provides long term assistance to members of the military and their families. The issues faced by veterans, both medical and social, are often chronic and require a lifetime of support. This is in a way a constant emergency for them and their families, and the US Department of Veteran Affairs aims to provide the necessary support.
