What are landslides?
Landslides are mass movements in which a large amount of soil is released from the rest. This phenomenon occurs naturally, but is more common and disastrous in areas that have suffered human intervention.
Causes of landslides
During the rains, the soil absorbs water and the rest flows on the surface in the form of runoff. Soil saturation occurs when all the pores in the soil are filled with water, making it unstable and prone to landslides.
In addition, areas of damaged relief with shallower soils are also prone to landslides. Human factors such as deforestation and construction on hillsides also increase the risk of these disasters.
Preventive measures to avoid landslides
In areas that are not being occupied by housing, landslides do not have more serious consequences than the loss of some trees.
However, in urban areas, these phenomena can lead to the death of many people and cause enormous damage to homes, roads and local infrastructure.
To avoid landslides, it is essential to have good urban planning, investment in engineering works and an adequate housing policy. In addition, areas with a high risk of landslides must be vacated and the local inhabitants must be relocated.
Areas that have a lower risk, but are still susceptible, may remain occupied, but it is necessary to demand the construction of retaining walls and a better drainage infrastructure.
Conclusion
Landslides are a serious problem in Brazil, causing material and human damage. It is necessary to adopt preventive measures to avoid these disasters, such as urban planning and raising awareness of the population about the risks of occupation in areas at high risk of Slipping.
Only in this way will it be possible to guarantee the safety and well-being of all.
