When a disaster hits an area the demand for many goods and services will rise. These goods ara mostly basic necessities and demand will rise for them as a result of the disaster. This demand is likely to be stimulated by the people who were directly affected by the hazard. This is a good phenomena as producers see that demand for their products is expanding and so they charge higer prices knowing that people have little alternative but to keep on buying.
