Hurricanes are a lot harder to talk about deaths since hurricanes are so big and cause such widespread damage (although Hurricane Maria is supposedly responsible for around 3,000 deaths), but the economic impacts are much, much larger. Just one hurricane can cause hundreds of billions of dollars in damage [3].

I'm absolutely not arguing in favor of getting rid of FEMA, but there are definitely the costs of some natural disasters that could be avoided by relocating population centers. Although tornadoes are not one of them, in my opinion. The cost and death toll just isn't that high for a tornado.
