FEMA NRI 8-hazard radar - Dyer County
How to read this radar
The radar plots Dyer County's relative exposure to the eight headline natural hazards used by the FEMA National Risk Index. Each axis is the qualitative NRI risk rating (Very Low through Very High) re-expressed on a 0-100 scale so that the polygon shape lets you compare a county against another at a glance. A rounder polygon means broad multi-hazard exposure; a spiky polygon means one or two dominant hazards drive most of the modeled risk.
