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 IHS mainly focuses on disaster prevention and preparedness with initiatives such as teaching children about illness prevention, teaching about safe drinking water and food safety, preventing the spread of disease, and preventing injuries. They also have a number of resources available to their members to connect with healthcare professionals. This seems to be a community awareness type approach that prevents the spread of disease by teaching the community. It resembles that of many healthcare systems and does not seem to suggest problems with other approaches.

One major point outlined in the article is the way that disease outbreaks have been viewed and prepared for has changed over the past few centuries. It started out in the view of public health where social factors like sanitation and clean water were valued but then shifted towards preparedness after outbreaks of various influenza viruses seemed to not fit the paradigm of public health.

The organization has the infrastructure of the Federal government, however they operate in areas that are more rural, including Alaska and the Southwest where environmental issues such as clean drinking water can be present, which they address in their community health approach. All members also are allowed access to the internet, which I'm assuming is available at each of their locations.
