Disaster

A disaster is an event that causes serious harm to people, buildings, economies, or the environment, and the affected community cannot handle it alone.[1][2][better source needed] Natural disasters like avalanches, floods, earthquakes, and wildfires are caused by natural hazards.[3] Human-made disasters like oil spills, terrorist attacks and power outages are caused by people. Nowadays, it is hard to separate natural and human-made disasters because human actions can make natural disasters worse.[4][5][6] Climate change also affects how often disasters due to extreme weather hazards happen.
