When discussing disaster risk management, a disaster can highlight the following in a community:. In the technical sense, it is defined through the combination of three terms: hazard, exposure and vulnerability. In some countries, such hazard areas outline the geographic extent of floods that have a year period of possible return. Any people, assets, infrastructure, and ecosystems located inside the area are all exposed to potential damage from floods. The degree of potential damage is then characterised by the area's vulnerability.
