"Hazard mitigation refers to any sustained action taken to reduce or eliminate the long-term risk to human life and property from hazardous conditions. The following list of possible hazard mitigation measures for communities is compiled from experience and discussion within the states of FEMA Region 5: Illinois, Indiana, Michigan, Minnesota, Ohio and Wisconsin. The list of hazard types and ideas starts generally with coverage of natural hazards, such as flood or earthquake. These are followed by types of man-made and technological hazards. As extensive as this list is, it does not preclude other ideas for activities to save lives and prevent or reduce damages in the future. Many of the ideas are developed in other FEMA publications, including www.fema.gov, as well as in publications of other federal and state agencies."
