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.

1) Janey Ensminger Act: the act, finally passed in August of 2012, provides health care to veterans and family members who were exposed to contaminated water while in residence at Camp Lejeune. The bill specifically lists illnesses linked to the chemicals found in the water supply, thus does not extend unlimited coverage to all former residents. Moreover, those who receive care under the bill must have resided at Camp Lejeune for 30 days or more.

2)The Few, The Proud, The Forgotten: a website created in order to inform Marine/Navy personnel, dependents, and civilian residents of Camp Lejeune exposure. The website also seeks to help these individuals understand their rights under the legislation and as victims. It also provides an illness registration and photo gallery, demonstrating itself to be a page dedicated to informing all aspects of these incidents.

3) TCE: as a former organic chemistry TA and student, the chemical nature of TCE and other VOC's intrigues me. As a student of physiology, it's important to understand how certain chemical properties can effect the body; particularly in regard to pathologies that could arise from exposure. As a halocarbon, the compound demonstrates relative stability and has many industrial uses; however, this stability causes difficulty in disposing, as they do not readily degrade in typical environments, leading to accumulation. Moreover, TCE has specifically been shown to work as a central nervous system depressor. Its interaction with electrical regulation of nervous cells (and thus, action potential propagation) causes a general anesthesia effect-- leading to depressed functioning of the CNS and, in high enough doses, suppression of cardiac and respiratory function. It should also be noted that the cardiovascular system primarily operates under electrical control as well, resulting in a possible link between TCE exposure and arrhythmia

Emergency response is not specifically addressed in the article. However, medical professional-patient relations are a key component of emergency response; as such, Dr. Good's assertions surrounding patient narrative should be taken into consideration in emergency situations. He notes that the methodology and cultural nuances of narration can provide a cornucopia of information that would otherwise be ignored.

This report has been cited by 22 other works-- including articles, books, reports, reviews, and studies. This includes several these, book chapters, and dissertations. It appears mostly in anthropological and STSS works, indicating it has yet to move from these social sciences into the realms of policy.
