Not just “natural” consequences
The list of natural disasters includes drought and water shortages, wildfires, floods and tsunamis, landslides, thunderstorms, hail and lighting, hurricanes and tropical storms, tornadoes and damaging winds, earthquakes, and extreme heat / cold. In Wikipedia’s definition, a natural disaster is “a major adverse event resulting from natural processes of the Earth,” but then an adverse event is only a disaster “if it occurs in an area with vulnerable population.”
So if Typhoon Haiyan would have hit an island unpopulated by humans instead of smacking into the central Philippines, which is home to millions, we wouldn’t be talking about the “widespread devastation of a natural disaster.” In other words, it’s not “nature” that is undergoing the “disaster,” but humans.
