This essay scaffolds a discussion of how COVID19 is unfolding in India. A central question this essay hopes to build towards is: If we examine the ways COVID19 is unfolding in India, does "Ind

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.

In this article, It talks mainly about New Jerseys CSO communities and how the CSO's are and have been making steps towards reducing overflow and even though the current solutions being used right now is a way to help reduce the overflow, these systems are also major sources of water pollution. however, CSO's plan to help reduce overflow and help prevent extensive damage from hurricanes will, be beneficial to the public even though it may take a few years for it to be completed and be of use to the public.

one of the main issues that presents itself when hurricanes do occur is that the drainage systems become very clogged and end up flooding the streets. In response to this, on July 1, "new state permits went into effect for the 25 municipalities, sewage treatment plants, and sewage authorities that manage systems with CSOs. In addition to the steps these entities already have taken to control overflows, they now must develop comprehensive Long-Term Control Plans." (paragraph 5) If everything is able to function properly, we will be able to unclog the drainage systems allowing for the roads to not flood and people to move around if need be.
