Week 13: Coastal Hazards in Mexico

Storms, tsunamis and other natural hazards can ravage coastal communities. The costs of this damage are increasing because of the huge and growing investments in the coastal zone. Human communities and coastal ecosystems are at even greater risk as hurricanes become more frequent and intense as an effect of global warming,especially along the Gulf of Mexico. Historically, the coastal population's vulnerability to hazards has typically been managed through structural or engineered approaches.


Coastal Hazards are quickly becoming a dangerous threat along the Gulf of Mexico.

Wetlands scattered throughout the coastline of the Gulf of Mexico are quickly eroding and becoming inhospitable literally and economically to the current residents as the freshwater depositories become inundated by saltwater due to wetland degradation. This area of ‘marginal-sea type coastline’ is quickly slipping away, destroying the likelihood of communities depending on usable beaches, freshwater and saltwater seafood environments.


 The current plan as many have stated  is that avoiding events like the Deepwater Horizon, cutting down on structural interference on rivers, wetlands, and swamps, and supplementing of sand along beaches and sand dunes to help combat inundation will be a good course of mitigation.

Week 10 Extreme Weather

The country I will be focusing on is the United States and the natural hazard will be thunderstorms.
A severe thunderstorm is defined as a thunderstorm that includes a tornado, and/or winds of at least 58 mph, and/or hail of at least 1 inch in diameter. All thunderstorms, whether or not they're officially defined as severe, contain lightning.

Something quite interesting that I found while doing some research was that there were severe storms and a few tornadoes forecast to take place across portions of the southern Plains and Southeast over several days. The Storm Prediction Center placed areas from Kansas to Alabama under a risk for severe storms on Friday (3/24/17) and Saturday (3/25/17). The risk of violent storms on Friday will extend all the way from central Kansas and western Missouri to northeastern Texas and western Louisiana, according to AccuWeather. On Saturday (3/25), the worst of the severe weather was in Mississippi, Alabama and Louisiana.

So far this year, severe weather has been much worse than usual in the U.S. As of Wednesday (3/22/17), there have been a total of 369 reports of tornadoes across the country, about double the average, according to the prediction center. Reports of hail and wind are also twice the average.
