                         Brazil stories exist since 1671. Nowadays, it is just known that 
                         the majority of the mass movements in the hillsides occur in rainy 
                         periods, what makes the water the most important deflagrator agent 
                         of these movements, decreasing the soil resistance, increasing its 
                         specific weight and increasing the internal pressures as well. In
