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.

This arguement is supported by looking at 4 specific case histories and examining the factors contributing to the investigations in each.

1. The 1814 Burning of the Capitol Building - Investigation of the disaster conducted by one engineer, B.H. Lathobe, who was given vast resources with very few obsticles, except for financial constraits and an impatient congress, to complete his investigation and reconstruct the building. 

2. 1850 Hauge St. Explosion - After a major boiler explosion in Manhattan's Lower East Side, a pannel of "jurrors" and "experts" were called together to complete investigations, bring forth the history of the fauty boiler, and place the blame for the accident in an effort to "memorialize the dead and bring them justice." Because of the way this investigation was conducted, the blame could not be accurately placed so everyone involved was blamed for the failure.

3. 1903 Iroquois Theater Fire - John Ripley Freeman, a fireproof engineering expert and factory inspector, was brought in to complete a report and provided one of the first "modern" scientific disaster investigations. He utilized a new network of investigators, engineers, insurance companies, testing labs, and inter-industry coordination that characterizes modern disaster investigation.
