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 product is designed in the way that the portable bridge can be expand from a folded mode to a bridge length takes up to across a river. It expanded in a scissor-like (90° turned scissor lift) action, then slides out the decks with end-to-end to provide platforms for vehicles.

This design is “Made of aluminum alloy and steel, it’s lightweight and easy to transport, yet sturdy enough for cars to cross.” [1]

They worked with a social ecology that is consider closely related to federal government, by control and prevent the issues can assist government boost the employment rate and further with economy boost.

The film has not included the patient’s viewpoint or the locals’ viewpoints within this kind of situations. This might due to the communication difficulties with the language. If the audience viewed the content with locals’ viewpoint might benefit from knowing the cultural practices and plan for the future interaction more carefully.

From the search of app store on my phone, there is no app has similar function as Cloud9 does. Most of the apps just provide facts and general treatment to the user but not the interactions with parties like Cloud9 does.
