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. 

This film is directed towards the general public because of its emotional appeal. It does not have much dry, scientific data, which allows for a more general audience (as opposed to only those who are scientific). It is also targeted to an older population due to the graphic footage of the police shooting the children.

More statistics and research studies would have helped. Havng national information and numbers could have helped people take away more of an understanding and have an educational aspect.

OSHA covers most private sector employers and their workers. They also cover some public sector employers and workers in the US and other territories under federal authority. Those districts include DC, Puerto Rico, the Virgin Islands, American Samoa, Guam, and other islands as well. 

Workers at state and local government agencies are not covered by federal OSHA, but have OSH Act protections if they work in states that have an OSHA-approved state program. OSHA also permits states and territories to develop plans that cover only public sector (state and local government) workers. In these cases, private sector workers and employers remain under federal OSHA jurisdiction.OSHA’s protection applies to all federal agencies and does not cover self-employed individuals.

I researched,

1. what actually caused the collapse of the World Trade Centers
2. John Ripley Freeman and the creation of Underwriters Laboratories. 
3. The Hague Street Explosion

The data presented is from governmental texts, but we do not have a bibliography to assess. However, from the references and quotations made within the chapter, I can deduce that Fassin did a lot of research using extensive resources to gather information for this chapter. 

I was able to find that this article was cited in 51 other publications or papers. While many of the publications also discuss the shortcomings of disaster response in Katrina, others citation examples include studies involving anthropology, aging, or security issue. This article also is used as a way to highlight Katrina and how to prepare for future disasters. 

The bibliography for this report is extensive, with 5 of Galea's work used as a citation. Most of the citations are scholarly journal articles, showing that these authors did in depth research to form their discussion and arguments. 

Through her field work, the author is able to create a concise argument by using interviews and anecdotes by those affected by the disaster in Chernobyl. She also highlights aspects of the disaster itself, highlight pre, peri, and post events that had an impact on the area and populations exposed. She also provides some data regarding an increase in clinical registration of illnesses that have occurred under the title "symptoms and other indequately known states", that show a sharp increase after the event.
