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.

The EPA has a large impact to help minimize the hazard. one of the few things that they are doing is provinding the "critical science to develop and implement outdoor air regulations under the Clean Air Act and puts new tools and information in the hands of air quality managers and regulators to protect the air we breathe." also, the EPa designated areas that meet and dont meet the the standards for the PM standards and ozone standards.

Newark recommends to have things like handy in case they are needed:

  • flashlights
  • batteries
  • a first aid kit
  • emergency food and water
  • a non electric can opener
  • medicines
  • cash

they also recommend to put these things in a room that you deem safe along with a battery operated tv/radio, charge all your electronics and turn all the propane tanks in your possession off before the storm

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.

Officials are looking to change something like the trucks within the port industry in Newark to counteract air pollution while keeping in mind the jobs of many who can be affected by the changes. The port of New York and New Jersey supplies 270,000 jobs and $36 billion in economic activity for shipping. If the possible changes were implemented, they must make sure that this industry is not impacted negatively because that can hurt the communities connected to the industry.

To help the government with air pollution, people can try to use their cars less. This can be done through walking, biking, or carpooling to their destinations. This will help lessen the usage of fossil fuels that decrease the air quality. Although this may not seem like much, if more and more people begin to do this, eventually the results will begin to show
