Seismic St. Louis

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 implication that this policy have are all medically necessary health and mental health care expenses of an individual with respect to a WTC-related health condition (including necessary prescription drugs). It offers people a series of health helping and similar supports for people if there is another impacted terrorism.

It used recording data for 455 married or cohabiting persons who were from 23 counties of Mississippi at the time of Hurricane. There are also a highly experience epidemiological survey team and seven local interviewers who underwent training in general techniques participated the interviews. The study was approved by an Institutional Review Board. The data was measured using the PTSD module of the Composite International Diagnostic Interview for the Diagnostic and Statistical Manual of Mental Disorder. Following the reference, it was modified in connected to the Hurricane Katrina.
