Why do study it?


The studies about the movement of tectonic plates and climatic changes are essential and very important.
It is not just "Earth", but a living world in continuous movement and changes. The only planet known to us with climate and environmental conditions favorable to the organic life.
By studying the physical and climatic events, we can learn to monitor our living world, we can learn how the physical and climatics events are acting in our world, in the biology of the surface of our planet.
The Planet Earth takes millions of years to change much in relation to its old form.
Imagine a small insect that lives in a tree. Its life cycle is two weeks. During its lifetime, the insect does not witnessed any significant change in its treeland like the growth of the tree. It witnessed only some leafs falling. The same occurs between man and Earth. Big changes as the emerging of mountains and the dance of the Earth will never be perceived by a man in his lifetime.
That's why the collecting of data and studies are so important because through them we can better understand how the Earth works by the saved informations during the past of centuries.


Brazil and earthquakes


Brazil is a bit far from the edges of the South American plates

in a region where the plate has a thickness of about 200km and therefore high intensity earthquakes are very rare. That does not mean that Brazil is free from earthquakes because there are tectonic faults which makes Brazil vulnerable to earthquakes, but with low intensity compared to some neighboring Latin American countries around the world who suffer from the geological movement.
In the twentieth century there were more than a hundred earthquakes in Brazil.


Take a look:


One thing that really puzzles me is that the number of earthquakes in the world is ever increasing and growing more furious. The same is happening with nature in recent years. The number of floods and natural disasters is growing. Only last year have been about 17 earthquakes in Brazil. Most were of low magnitude, as almost always, but the number of earthquakes is increasing
Bellow you can see the largest earthquakes here in Brazil since the twentieth century:
