Natural hazards are severe and extreme weather and climate events that occur in all parts of the world, although some regions are more vulnerable to certain hazards than others. Natural hazards become disasters when people’s lives and livelihoods are destroyed.

Coastal inundation occurs along vulnerable coastlines. The combination of storm surges – typically from tropical cyclones or extratropical storms – and waves, with riverine flooding at various tidal states regularly leads to major loss of life. At least 2.6 million people are estimated to have drowned due to coastal inundation caused by storm surges over the last 200 years (Dilley et al., 2005).
