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.

Newark helped to set up the JFK Center as a shelter with the help of the American Red Cross. further more, "Booker also urged residents to check on their neighbors, particularly the elderly, to be sure they have adequate supplies and protection during the hurricane"

many recommendations are also being made by the city of Newark to advize their citizens

There were several forms of resilience int eh article. The Federal Emergency Management Agency (FEMA) were preparing several emergency personnel are preparing all along the coast. In addition to this, there were several shelters open, one specfically at the John F. Kennedy Recreation Center. Many of the shelters had also teamed up with Red Cross to help during the storm.

as stated in the article two things have been done to help prevent sewage in overflow systems.one is that, "Nearly 65 overflows already have been permanently closed off, according to the Dept. of Environmental Protection." also, many other communities spent millions of dollars to install grates and shields on the overflow pipes. this would help prevent most trash from entering the system.

The author of the article took several quotes from government officials to depict the severity of the situation: mainly taking quotes from governors and even the president to illustrate how the hurricane affected the surrounding communities and mentalities of those living in such towns. In addition, the author added statistics of the support relief and the number of deceased due to the storm. The author also discussed the background of many of the public transportation work shifts, such as airlfight and train systems: they were down becuase of the storm.

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.

The largest risk at hand would be how the nautral disaster, Hurricane Sandy, affected the beaches of New Jersey, causing some the beaches to lose a significant amount of sand; this becomes a risk because the beaches weren't available to use. The beaches of New Jersey make most of the profit in tourism: the shore gaining $35.5 billion for tourism locations. This became a risk becuase there was money lost during and after the storm, as groups tried to repair the shores. In addition, the cost to repair the shores were extremely costly. Another group that received risks and hazards were the communities near the shores: they had to change their entire lifestyle when the beaches were destroyed after the storm. Those communities had to learn how to live without the beaches' resources and had to get accustomed to not going down to the shores while the beaches were being restored.

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

After the storms, many towns affected came up with ways to increase protection in infrastructure. Town officials working alongside exerpts have been working to upgrade their plans on making their communities more resilient to natural disasters. There have also many several funds and donations for the towns affected by Sandy; there have also been ways on how to help prevent flooding in such areas. In the article, it discusses how "the DEP has worked with local officials to design a proposed $230 million federally-funded system of flood walls along the Hudson River for Hoboken and parts of Weehawken and Jersey City."

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.
