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 artical shows the political and government really influence the people's health and emergency. Haiti's government disappointed all the other oganisations and it makes the restore difficult after the eaarthquake and cholera epidemic. The artical descrpites the situation and fact in the 5 years after the disaster. In addition, the reactions of the involved organisations such as United Nations are shows the problem and the result that where the money go. There are also applied examples to support why the donation are not final go to the Haiti's people, and Haiti's government is deal-killer. Apart from this, the artical shows if there are not enough economic fund and medical supporting after disaster, there might be a epidemic comes up, and make the situation worse. All the donation and support are should be in good organisation to help people and rebuild the environment.
