Mapping historical disasters

Recently, FEMA released a web mapping tool that allows you to track disasters in the United States in real time. But what about historical declarations? Yesterday, I stumbled across a webGIS that does exactly that. 

Data in this GIS goes back to 1958, predating FEMA by more than 20 years. For some odd reason, the timeline slider starts at 1991, but you can rewind further by clicking the tool icon to the left of the timeline and then clicking “show advanced options.” Press play and watch the disasters unfold.
