The occurrence of natural disasters like this gets a great media appeal, with reports showing strong images, the suffering of the people directly affected, their relatives loss, their homes and appliances and housewares. However a question that calls attention not counting the shock of the humanitarian tragedy are economic losses involved. There are some methods of valuation of damage to estimate economic losses.
