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.

    1. “…large­-scale social forces—racism, gender inequality, poverty, political violence and war, and sometimes the very policies that address them—often determine who falls ill and who has access to care.”
    2. "the holy grail of modern medicine remains the search for the molecular basis of disease."
    3. "In some senses, the model is simple: clinical and community barriers to care are removed as diagnosis and treatment are declared a public good and made available free of charge to patients living in poverty."
    4. "The poor are the natural constituents of public health, and physicians ... are the natural attourneys of the poor."

    1. I first looked up travel to and from Liberia during the Ebola outbreak, since it had been seized. There was a ban, which has since been lifted after, but people coming to and from West Africa are still screened and recommended to visit physicians. As of mid-2015 there wa still a 21 day monitoring period needed. http://www.infectioncontroltoday.com/news/2015/05/cdc-downgrades-travel…'
    2. I was interested if there had been any progress on treatment for Ebola, but found that the main form of treatment is supportive care. Doctors are informed to provide IV fluid and ensure that the patient's immune response and other bodily functions are functioning properly. A vaccine is being worked on but has not gone through a trial to prove safety and effectiveness. https://www.cdc.gov/vhf/ebola/treatment/index.html
    3. I looked further into the vaccine being produced for Ebola. Currently, there is a combined phase 2 and phase 3 trial occurring in Sierra Leone called STRIVE (Sierra Leone Trial to Introduce a Vaccine against Ebola). The study is unblinded, so patients know whether or not they have received the vaccine. The vaccine is a rVSV-ZEBOV, or recombinant Vesicular Stomatitis Virus Zaire ebolavirus vaccine. This vaccine is also being used in phase 2 and phase 3 trials in Guinea and Liberia http://www.cdc.gov/vhf/ebola/strive/qa.html

    The convention in 1951 was a response to WW2 and the vast amounts of refugees that existed as a result. States involved in the convention and the UN could decide to apply it to refugees not necessarily from WW2, but in 1967, the limits were removed and made it so that it could apply to any refugees, not just those from WW2. It has since been used during major refugee crises in Africa, the Middle East, and Asia.
