what is natural disaster?
a natural disaster is a natural hazard that has actually happened
two types of natural hazard
geological hazards-hazards to do with land and tectonic processes (volcanoes,earthquakes...)
meteorological hazards-hazards that are caused by the weather and climate (tropical storms...)
factors that affect hazard risk
vulnerability-(closer you are more damage or the more people the more damage.....)
capacity to cope-(e.g HIC are better able to cope so there is a lower risk of them being affected)
nature of natural hazard-(type,the risk of some hazards are greater then others)
the primary affects of a natural disaster are their immediate impacts caused by the hazards (buildings destroyed ,roads damaged....)
secondary effects happen later on ,often as a result of primary effects (e.g food shortages cause of damaged crops , lack of jobs as buildings of companies have been damaged)
