Earthquakes in Brazil

Compared to some of his neighboring countries, Brazil is practically immune to natural disasters. All Brazilians volcanoes have been extinct for several million years (more about that here). As far as registers go, the country never witnessed a hurricane, although a first cyclone, dubbed Catarina, killed a few people and destroyed 1,500 houses in 2004. Floods are the only recurrent natural drama and produce several deaths every year, but they cannot be attributed to an unexpected amount of rain. Most of the losses are associated to the inadequate occupation of mountains and river banks, plus government neglect.

Even earthquakes are discreet if compared to those registered in another country of South America, Chile. The reason is simple. Earthquakes normally occur in the borders of the tectonic plates, the huge rocks that lay under the surface of the earth. Chile is more exposed because it is on the edge of the South American plate while Brazil is on the middle of the same plate, a much stabler place.

Check this image produced by the US Geological Survey and you will see that Brazil has only a few yellow circles – quakes with almost negligible impact. Continue reading Earthquakes in Brazil
