Brazil coastal hazards

A study was conducted in the North East state of Para in Brazil. The study concluded in the last 25 years there was numerous   evidence of natural impacts in the flood and erosion process. Strategies and measures of population adaptation have been implemented, but had limited success. In order to subsidize the Coastal Zone Management Program of Para, natural and socio-economic vulnerability of costal zone buy means of a Geographical Information System based composite coastal vulnerability index. In spite of the data problems and shortcomings, using ESRI's 3.2 program, the CVI score, to classify, weight and combine a number of 16 separate natural and socio-economic variables to create a single indicator provides a reliable measure of differences among regions and communities that are exposed to similar ranges of hazards. The results are presented in 3 maps referred to as Natural, Socioeconomic and Total Vulnerability.

    I use GIS all the time...great software to map anything...

    The human attempt to prevent coastal erosion when we have altered the way the process would naturally occur looks pretty much futile. In sand beaches the most sure way to maintain their existence looks to be replenishing sand yet this is costly and in the even of large storms it the brunt of the work can be undone. The use of mapping software surely helps in understand what exactly is going on and where should coastal restoration efforts be focused.

    Hi Ryan,
    Great post, I personally love Brazil. To think that so much can happen there since the country is mostly a coast. The information abut the GIS was new to me, and I tried it and leaned a lot. Keep up the good work!

Tectonic Plates

Brazil is located on the South American Plate. The South American Plate covers all of South America. To the west of the South American Plate is the Nazaca Plate. In addition, the African Plate can be found to the east of the South American Plate. As you can see in the image below, the South American Plate and the Nazaca plate both shift towards each other. In 2015, The South American Plate was responsible for a 7.6 magnitude earthquake that shook the Peru-Brazil boarder.  The eastern side that goes along the African Plate is a divergent boundary. The west side of the plate is a convergent boundary. The northern side is a boundary with the Caribbean Plate is an oceanic crust the North American Plate.

Week 3 Earthquakes

Brazil is located on the South American Plate. This mid-plate region is known to be the least active stable continental regions in the world. The biggest earthquake they had was recorded at a magnitude of 6.2 mb. In Brazil, you can identify several seismic zones. this also includes carton edges. Brazil has a seismic-building standard that has been enforced since 2006. However, that was based  on the outdated seismic hazard map. Therefore, researchers are suggesting that Brazil update their building codes in order to prevent low-intensity tremors from causing damage RESOURCES: http://www.homelandsecuritynewswire.com/dr20170823-a-new-map-of-seismic-hazards-in-brazil-shows-that-new-building-code-is-required https://www.researchgate.net/publication/266393548_Intraplate_seismicity_in_Brazil
