The Degg's Model shows that a natural disaster only occurs if a vulnerable population is exposed to a hazard. [1] It was devised in 1992 by Martin Degg, [2] head of the geography department at the University of Chester, in England. It also depends on how far people are from the epicentre of an earthquake, volcano, or any other natural tectonic ...
Hazard maps are created and used in conjunction with several natural disasters. [1] Different hazard maps have different uses. For instance, the hazard map created by the Rizal Geological Survey is used by Rizalian insurance agencies in order to properly adjust insurance for people living in hazardous areas. [2]

Flooding is the greatest natural hazard in New Zealand , [94] and its control is primarily managed and funded by local councils. [95] Throughout the country there is a network of more than 5284 km of levees, [96] while gravel extraction to lower river water levels is also a popular flood control technique.
A bow-tie diagram is a graphic tool used to describe a possible damage process in terms of the mechanisms that may initiate an event in which energy is released, creating possible outcomes, which themselves produce adverse consequences such as injury and damage. The diagram is centred on the (generally unintended) event with credible initiating ...
