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. 

"If I`m driving and I don`t want this bottle in my car..throw it out the window.." (Wolfe line 30) - This shows how easy it is to litter and how there are many people who littler like this individual, disregarding the fact that they may be creating a bigger problem in the near future - lots and lots of trash.

"Residents need to do their part in the cleanup effort" ( Wolfe line 40). - This describes a possible solution the problem. If everyone resists littering and cleans up after themselves and do other things like recycle, the problem may persist but the amount of garbage may be less than the current amount.
