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.

Several historical examples are used including the burning of the US Capital in 1814, the Hague St. explosion in 1850, and the Iroquois theater fire in 1903. The article uses examples that were in the public awareness at the time of the disaster in order to exemplify the many agents pressuring investigators to make a rapid and acceptable decision including the public, the government, and the businesses effected.
