World map of natural hazards
A natural hazard is a natural phenomenon caused by events that might negatively influence humans and other living organisms or the environment. Natural hazards can be classified into five broad categories: geophysical (earthquakes, mudslides, landslides, and volcanic activity), hydrological (avalanches and floods), climatological (extreme temperatures and drought), meteorological (storms, tornados,) and biological (disease epidemics and pandemics, and pest or animal plagues).
