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.

Q1. The report was basically about the how flood has been affecting newark over the past years and the adequate control measures/techniques (laws Movements,permits)

that have been put in place to ensure the prevention of flood in Newark.Agencies that prevent flood have also proven efective and functional over time as in indicated

in the text "Historically, New Jersey has taken a strong role in the development of a rigorous floodplain management program at the State level while supporting those

same efforts at the Federal level with the Federal Emergency Management Agency (FEMA) "(Floodplain Mapping Unit paragraph 1).This report would make resident feel

at ease knowing the problem of flooding is uder control.

Reacting to this report, Although Its is very reassuring knowing all these Agencies,funding,laws, and concerns are in place, I believe extra effort should be put in not only

in Newark but also in other flood affected areas in New Jersey and The United States as a whole because water levels are rising (major concern in coastal areas)and new methods should be put in place to

avoid major casualties.

Air polluion involves the introduction of harmful substance into the air.These harmful substances

involves various harmful gases let out by machines, aircrafts and so on.

These pllutions could lead to serious health injuries which could lead to poverty if

too much money is spent in the hospital as treatment could be expensive.

Industrial Waste In Newark

This Pece Essay talks about how industrial waste water is affecting the rivers and a major water way, the Passaic River.
