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.

“I wrote about personality and how it might change on medication.”

“We need storytelling, to set us in the clinical moment, remind us of the variety of human experience and enrich our judgment.”

“In psychiatry — and the same is true throughout medicine — randomized trials are rarely large enough to provide guidance on their own.”

“It has been my hope that, while we wait for conclusive science, stories will preserve diversity in our theories of mind. “

The article shows there are no specific nuclear emergency plants or Indian Point Disaster. The arounding environment is densely populated and no material educational to resisdent. The situtation are illustrated by image and quotations of many different representors. The main point is as the title shows, to urges expanded emergency planning for Indian Point disaster. The important thing is federal government need to support and guide the state and organisations.

Smart Guardrail is considered as a good concept design, because it can be solve the emergency problem for traffic accident in some situation. This design is applied a common materials and method to solve problem. It is a small change and might make a big influenced. But the design could be used or not is depend on the cost would be proportional to the value or not.
