Towards a Better Understanding of Hurricane Disaster Risk: Assessing the Inland Hazards Associated with Hurricanes in the U.S. Atlantic Basin
The specific hazards of TC-associated flash flooding (TCFF) and tornadoes (TCT) are assessed over approximately the last two decades using GIS. The highest TCFF hazard is indicated in southern Mississippi, Alabama, North Carolina and the Mid Atlantic Region, and TCT hazard is highest in the same region as TCFF, including Florida; stream-gage data additionally show that the highest TC-flood potential is in southern Florida. The TCFF and TCT data are smoothed at a county/parish level and then combined with a quantification of the social vulnerability of the exposed populations to derive a hurricane disaster risk index. The disaster risk index is also used in experiments with agent based modeling to assess evacuation behavior.
