A hazard, (in geologic terms) are conditions that are dangerous for humans, animals, and wildlife. Hazards may be occur suddenly, like a volcanic explosion for example. Or, they can be slow forming hazards, such as land erosion near property.
A disaster is the outcome of geologic events which cause loss of life, property damage, cause of fire.. etc. Examples of natural disasters include tsunamis, earthquakes, volcanic eruptions, and cyclones.
A catastrophe is a violent event that affects immense amounts of people, and it also effects the geological landscape. A catastrophe takes years and mass amounts of years to make a full recovery.
