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 bar graph shows that blacks have the lowest median household income out of all races.  This means that they are at most risk of hazards, they are most affected by poverty, with Hispanics being the second most affected.

This study is published the Environmental Health Perspectives.  The journal helps explain the continuity between human health and the environment.  They publish topics like toxicology, epidemiology, exposure science, and risk assessment.  The publication is ranked highly among professionals and has a rating of 8.44. 

Food stamp (SNAP) rolls increased over the years, and the article addresses that this is a sign of poverty.  The USDA is an agency that administers food stamps.

The Supplemental Nutrition Assistance Program (SNAP) and Women, Infants, and Children (WIC) are two agencies that many low-income families are enrolled in.  WIC provides nutritious food for pregnant, breastfeeding and postpartum women, infants and children up to the age of five; it is specifically available for household up to 185 percent of the federal poverty lines.  SNAP provides low-income families with nutritious food.

This study determines if childhood blood lead levels correlate with educational achievement.  They studied this through standardized test scores.
