Here we consider which severe weather events in the US have the most impact, in terms of fatalities, injuries, property damage, and crop damage. We first find the events which have the greatest number of fatalities within the entire US, and then break this down by state. Then, we find those events which have the largest amount of property damage across the entire US, and then break this down by state. We discover that most fatalities come from tornados, heat. flash glood, and excessive heat, but these are problems only in specific states . We discover that most property damage comes from thunderstorm winds, tornados, floods, and flash floods, but again, concentrated in specific states. Perhaps this could be useful in analyzing how resources should be allocated to deal with these extreme weather events.
