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.

There are four regions of microbial threats that the paper focuses on: emerging infectious disease; bioterrorism; life sciences; and food safety.

Huge increases on spending in the US on biodefense from millions to billions of dollars

Very general emergency response plans have weaknesses in that they are so quickly applied to any situation without considering what a specific region needs, has, or lacks.

The real threats of air quality were covered up due to politics and other reasons, wanting to get america back to work. Instead, the reports were edited and people were sent back into the dirty air to clean up the scene or back to office jobs in the area, with contaminated air surrounding everything. Decontanimation efforts did not start until very late in the process. Bush did not wear a mask and the workers were told they didn't need to, so they didn't. As a result, there were severe health problems afterwards.

It was created to further outline the uses and resposibilities of medicaid, specifically with IMDs. It places more responsibility on the states for middle-aged people in need of this type of care, rather than the federal government. These changes and specifications occurred throughout the 1970's and 80's, when mental health was becoming more of an understood issue, and treatment of those with mental diseases was being improved.
