Brazil's Main Natural Hazards

Flooding and Mudslides
Brazils main natural hazards are flooding and massive mudslides. Heavy seasonal rains in Brazil lead to flooding and these flash flood events, along with poorly built towns result in mudslides that destroy thousands of dollars worth of infrastructure. According to Brazil’s meteorological agency, INMET, excessive amount of rain is the product of Brazil’s location in the South Atlantic Convergence Zone and is strongest in their warm season. This It causes thunderstorms in the Brazilian rainforest and surrounding areas during the summer. However, the amount of rain that has fallen over the region has doubled the historical rainfall rate that has been recorded by INMET for the past 40 years.


Preparing for Flooding and Mudslides
Flash flooding is a frequent hazard in Brazil. As urbanization increases, more property owners are looking for protection. Urban planning has never been part of Brazil's political agenda, therefore when rain season come around cities are not able to cope. In the mountainous region of Rio de Janeiro many of the cities in the area deal with isolation during rain season because of poor city planning. Hundred of citizens in this region die as a result of mudslides while their neighboring state São Paulo, a prominently wealthier region, deals with little to no deaths. This is one of the many examples of how poorly Brazils government distributes its money throughout the country. 
One of the first steps Brazil must take when managing the results of floods and mudslides is helping the poorer regions rebuild their homes in a way that will help them be prepared for these events. Their government only sets out plans to deal with the outcome, rather than plan and prevent. The idea of "long-term planning" is not often found in Brazils political dictionary. They focus more on "short-term" public works. The Supreme Court has showed some effort to set out and follow an urban plan. They have divided their subject axis into 4 sections

• Prevention – Constructions related to the natural disasters risk reduction - Development Acceleration Program.
• Mapping – Mapping of areas with high risk of landslide, flood and rushing stream of water. 
• Monitoring and alert – Observation equipments and situation rooms to improve the weather and hydrological forecasts and warnings. 
• Disasters responses – To improve the Government capacity to act in disasters occurrences. 


Regions of Brazil
Every part of Brazil deals with its own natural hazards, from droughts to flooding. When deciding where to live in Brazil it is up to you to decide what you rather deal with. Majority of my family is spread across different regions of Brazil. My aunt lives in the state of Ceará, where she says the experience very minimal flooding. Ceará is located in the northeastern part of Brazil, has a mountainous interior and an Atlantic coastline line. The average temperature for this region varies from 75°F to 87°F and rarely goes below 73°F or above 89°F. This is a warm region of Brazil that does occasionally experience droughts and flooding bur not near to the extend of the South and Southeast regions. These areas along with some parts of the North have to manage not only river flooding, coastal flooding, and urban flooding, but it also has to manage tsunamis and landslides.

    Hi Leti! This is very well done! It was very interesting to learn about the impact of flooding and mudslides on Brazil. I have to agree with you when it comes to deciding where to live. Every area you live in has its risks, so might as well live where you're going to enjoy living! Thank you again for post, and hope you had a great semester!

    Hey Leti! First off I just wanted to add that I extremely loved your blog and it was more than interesting to read! A similarity I noticed between our chose countries of Brazil and Nepal is their mitigation efforts consisting of the emphasis on infrastructure durability and how both of our countries are in the progress of building them. Both of our countries deal with flash flooding and the only true way to deal and prevent casualties and destruction from that is with constructions and mapping to where those constructions should go. Also forecasting is also a new vocal point on both of our nations plannings in order to predict and estimate when a threat is possibly nearby to warn its i inhabitants. Cheers!

Brazil's relations to tectonic plate boundaries

Image
Brazil is located on the South American Plate. This is the smallest of the major plates and is about 43,600,000km^2 in size. This plate includes the continents of South America and a large part of the Atlantic Ocean. This plate is bounded by the African plate in the east, Nazca plate to the west, Antarctic plate and Scotia plate in the south, and the Caribbean plate and North American plate in the north. The eastern side lies on the Atlantic Ocean at the divergent plate boundary (two plates that are moving away from each other and new crust is forming from magma that rises to the surface between them). On the other hand the west side of the South America experiences many harsh earthquakes because of the convergent plate tectonic boundaries (two plates that are moving toward each other). The South American Plate pulls apart from the African Plate and by doing this they create the youngest oceanic crust in the world (divergent). However on the other side the Nazca plate has overtime c...

Mass Wasting in Brazil

Image
Mass waisting also known as  mass movement, is the geomorphic process where soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity, frequently with characteristics of a flow as in debris flows and mudflows.  Landslides are natural processes triggered by complex relationships between many conditioning factors. Landslide in 2020 In Rio de Janeiro city, intense rainstorms combined with steep slopes, usually occupied by slums, create the perfect conditions for landslides.  Since January of 2020, heavy   rainstorms   in the   Southeast Region   of Brazil have caused flooding and landslides in the states of   Minas Gerais , Espírito Santo and   Rio de Janeiro.  The state capital of Minas Gerais,   Belo Horizonte , reported that this years rainfall is the highest it has been in over 110 years.   As of late January of 2020, at least 70 people ...

Volcanic Activity in Brazil

Image
Brazil's Volcanic Activity Brazil is located at the center of the South American plate, which means it is far away from the edges of tectoni c plates. Unlike Chili and other countries located on the continent’s western edge, and are part of the volcanic “Ring of Fire”. This is the reason why there hasn’t been any active volcanoes in Brazil in a while. W hile there hasn’t been any active volcanic eruptions in Brazil in recent years, there are many signs that suggest that the country has experienced volcanic activity in the past. Rio’s Sleeping Giant (O  Gigante Adormecido ) Just above Rio de Janeiro is the “Patole” which is a 60-mile-long sheet of pure granite that was formed by consolidated igneous rock from an ancient volcanic eruption. This was once a massive reservoir of magma but because it never made its way to ground level it instead formed the Serra dos Orgaos mountains. It is believed that in the past the Patole was a gigantic volcano but has since...
