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.

This policy has significant implications as to the future of EMS and fire response, if it became common to carry firearms while on duty. While there are safety benefits, and EMS personnel in Bethel Township say they are also more confident knowing they could defend themselves, it is important to recognize that police have extensive training and protocols on when and how to safely use their firearms. Police should still respond to EMS calls if there is any suspicion that the scene may be unsafe. Additionally, the knowledge that calling an ambulance also means calling several people who may be armed could negatively affect the public opinion of EMS. EMS is here to help the public, and for this to be successful those in need have to feel safe calling 911.

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.

The US Department of Veteran Affairs is constantly adjusting to new medical research to provide the most effective care possible. This shows a differing approach to emergency response which is only possible due to the long term nature of this organization, most emergency response groups focus on quick response to disasters which does not allow for the same amount of research and adaptation as the Department of Veteran Affairs.

  • Chernobyl was an unexpected disaster, however several more nuclear disasters have occurred since then. I looked into the safeguards that were changed after Chernobyl and if those had any part in mitigating other nuclear meltdowns. After the explosions several countries and international groups developed nuclear policies that attempted to prevent critical system failures as occurred during the test that caused the reactor to overheat, but many countries refused to adopt additional safeguards that may prevent future disasters.
  • The article described the various zones put into place to keep people away from the most radioactive areas around Chernobyl, I looked into the zones used and the determining factors in determining the sizes of each zone. The initial response determined a zone of 30km around the site, however as scientific understanding of radiation improved the zone was extended to 2600km. This shows the importance of an informed response to prevent further damage after a disaster.

Finally, I researched the effects of low dose radiation poisoning to better understand the medical care needed by those affected. Even low exposure doses can cause lasting damage to organs, or cause cancer and blood related illnesses through the effect of radiation on bone marrow. Those exposed would need frequent medical exams and treatment for the entirety of their lives.

  • Throughout the article it became apparent that the individuals being interviewed were rarely prescribed medication and in some cases did not take their medication. I researched the effectiveness of epilepsy medication and severity of not treating seizures in order to better understand that specific illness.
  • The article was written using data collected in 1988. Since medical knowledge has changed dramatically since then I decided to look into the current medical situation in Turkey. Although it is challenging to find unbiased opinions it appears that even with advances in medical science, cultural traditions remain an integral part in dealing with illness in many places and needs to be understood when dealing with patients who have those beliefs.
  • A majority of the patients interviewed attribute their seizures to a traumatic moment in their past, as I was unaware that epilepsy could be triggered in such a way I looked into the causes of epilepsy. In many cases the cause cannot be identified, however there is significant evidence for epileptic fits being caused by post-traumatic stress as well as neurological trauma and even cardiac issues.
