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 aftermaths of Sandy had created many vulnerabilites to the communities around the shores. There were about 840 million gallons of raw sewage scattered into the Passaic River; and since the sewerage system had struggled to get back to full operating hours and service, there were 4.4 billion gallons of partially treated sewage were released into New York Harbor. In addition, many infrastructure was severely damaged after the storm: houses, power substations, police headquarters, etc.

The main sources of resilience are: discussing the list of pollutants that are spread across through a demographic structure, how pollutants affect and become more apparent to different race and economic levels; the information about possible new pollutants that could appear due to the addition of new companies; and the reconstruction on the zoning laws in Newark. Additionally, there are numerous environmentalists of all types behind this new addition to the zoning and land use regulations.

Although this article talks about how NJPAC will donate money to the victims of the natural disaster, it doesn't include how the money will be used: will it be used to help support the people affected by the storm, help rebuild the building destroyed, etc? In addition, I feel as if this article is missing the key information of how severe the storm struck some places along the coast: by providing such information, it would create more awareness and allow a higher chance for the tickets to be purchased to help support the cause.

In the article, it expalins the various attempts of securing the area and preventing further damage from the storm. There were several plans of evacuation, shelters opened up to those in need, protection of federal troops were deployed and many towns offered relief help after the storm had passed.

The most resilience the beaches and the communities around the shores have are federal aid. There have been numerous plans and discussions on how to help reconstruct the shores of New Jersey. In addition, several Congress members and even the vice president at the time, Joe Biden, showed their want to help aid in the recovery of natural disasters.

"'Environmental Justice and Cumulative Impacts' is intended to create stronger environmental and land use policy tools at the local level to prevent and mitigate additional pollution associated with a variety of development and redevelopment projects. It also addresses environmental justice by helping to prevent Newark, which has a disproportionate number of low-income and residents of color, from having a disproportionate number of polluting projects placed within its borders" (Hislip par. 1).

"showed a graph developed by environmental justice community organizers, which detailed the differences between communities that experience pollution versus the predominant race of those communities, which showed that as the number of people of color or the level of poverty in a neighborhood increased, so too did the cumulative impacts. In New Jersey, the amount of pollution you experience is directly correlated to your income and skin color" (Hislip par. 5).

"She explained that zoning laws in Newark are slowly changing, including rezoning and getting rid of outdated rules that were grandfathered in. But the impacts from the pollutants that were allowed to run rampant are very evident. Before Newark’s zoning laws were updated in 2012, the last time they had been updated was in 1954 and therefore had little regard for quality-of-life issues. The Ironbound district later became a hotbed for environmental justice movements due to its adjacency to industrial areas. Many heavy pollutants that were planned for this area saw heavy protest from EJ activists, like automobile shredding plants and chicken crematoriums" (Hislip par.8).

"The ordinance itself requires individuals applying for commercial or industrial developments within Newark to take the following steps:

  1. Reference the city’s ERI and prepare a checklist of pollutants
  2. Submit checklist and development application to the city
  3. Checklist goes to the Environmental Commission
  4. Checklist goes to the Planning or Zoning Board (where appropriate)" (Hislip par. 9)
