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. 

Although reducing air pollution is very hard nowadays, however people can take precaution especailly in the way in which they use means of transportation in their daily lives. Eliminating air pollution is not possible but their are many ways in which we can reduce it. First off by choosing a better transportation method everyday, instead taking public transport, or driving your car when not needed. Suppose you want to make a quick food run to a place nearby, why not walk there or maybe even ride your bike, saving fuel and the emissions that would be emitted from them when you use those transportations. It is small steps that each person can take in their daily lives that would help reduce pollution overtime. Also getting out there and supporting causes that push for cleaner air, if each person played their part in their own communities instead of leaving it up to others, we would definitley elimiante a lot of waster. 

The aim of this organization is to address the problem of sewage overflows in the cities of New Jersey. They want to address these issues combining alongwith the aiding in water conservation, flooding resiliency measures, and solutions to innovative financing. 

• At least 56 people in the U.S. were killed and another 67 in the Caribbean.
• Cost estimates have ranged as high as $60 billion so far.
• More than 4 million people remain without power, as crews from across the country converge on the Northeast to restore electricity.

In an industrial city like Newark, although prevention of air pollution is hard, but control can be in our hands. By identifying the areas with the higher risks and also the people being affected by the poor air quailty, we can further give the community more clear information regarding the risks and also in turn influencing policy makers and the stakeholders of the community. Being correctly informed on the topic not only helps the community members, but also the people in charge of making decisions for their communities, making this a better way to work together to build a healthier ans safer community in areas like these. 

Yes, individual communities should determine the air quality standards for their areas because each area would have a different standard. For example the Newark area air quality standard would be much lower then the other tri-state areas of New Jersey. If Newark's air quality was measured with standards that are kept for the whole state then the results would be much lower and wouldn't be right to compare the two. Having different standards per each area helps in diffrentiating between each one.
