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 ...
A natural disaster is the highly harmful impact on a society or community following a natural hazard event. The term "disaster" itself is defined as follows: "Disasters are serious disruptions to the functioning of a community that exceed its capacity to cope using its own resources. Disasters can be caused by natural, man-made and ...
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]
The term natural disaster has been called a misnomer already in 1976. [6] A disaster is a result of a natural hazard impacting a vulnerable community. But disasters can be avoided. Earthquakes, droughts, floods, storms, and other events lead to disasters because of human action and inaction.
A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.
The concept of social vulnerability emerged most recently within the discourse on natural hazards and disasters. To date no one definition has been agreed upon. Similarly, multiple theories of social vulnerability exist. [6] Most work conducted so far focuses on empirical observation and conceptual models.
Natural disasters vs. human disasters The population that lives along or near coastlines is extremely vulnerable to coastal hazards. There are numerous issues that can threaten coastal ecosystems, with two main categories that these hazards can be placed under: Natural disasters and human disasters.
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 ...
