The disaster in the State of Rio de Janeiro was caused by not so concentrated but intermit-tent continuous heavy rainfall for a long time. Many people died and injured mainly in Petropo-lis and Rio de Janeiro by slope failures and debris flow. Many people are living in steep slopesaround Petropolis and Rio de Janeiro and some low lands in Baixada Fluminense which are notsuitable for house construction. This increased the damage of the disaster extensively.Flood control projects are proposed by the State against floodings in Baixade Fluminense andin the city of Rio de Janeiro. This kind of projects should be carried out as soon as possible.And effective countermeasures such as afforestation and sabo dam construction against steepslope failures and debris flows should be taken and the warning and sheltering system are desiredto be established as well as the improvement of consiousness about disaster prevention and refugeas a tentative measure. But social policy that the fundamentally needed because engineeringcountermeasures are difficult to be made due to weakness of the soil and steepness of the slopes.
