We have a rapid increase in human population, which pushes people to build in riskier areas. Most of these disasters have a probability of occurrence that varies with geographic location on the Earth's surface. Statistically, one can avoid earthquakes by staying out of those relatively limited geographic regions. One can avoid hurricanes by staying inland at least a couple of hundred miles from an ocean. Consequently, in the rest of the world, tornadoes are a relatively rare occurrence.
Flooding can occur almost anywhere, but it occurs least often in desert areas.
However, when flooding does occur in deserts, it tends to be flash flooding, which is the most dangerous kind of flooding because it develops very quickly, without warning. Warnings are provided in the US for tsunami, tornadoes, hurricanes, volcanoes, and floods. Pay attention, and be prepared. Avoid unsafe buildings and terrains. Building codes and zoning regulations are there for the greater public good.
