The study examines the dissemination of tornado warnings in Mississippi. Using Geographic Information Systems, this study seeks to display television, radio, cell phone, and outdoor siren coverage areas by using viewshed analysis and other tools to locate broadcast coverage gaps in order to develop an index that identifies areas of limited to no coverage. U.S. Census data will be used to examine demographic information in order to identify socially vulnerable populations. Tornadoes that resulted in injuries or fatalities will be identified along with their warning polygons, if warned. Statistical analysis will then be used to determine any correlations between socially vulnerable populations and hazard casualties, respectively, within the coverage gaps. The hypothesis is that socio-economically vulnerable citizens are more likely to reside within coverage gaps, and there are more casualties within warned areas that have coverage gaps.
