Disaster Disasters And Its Impact On A Population

1421 Words6 Pages
Disasters, at their most basic, arise when hazards have a significant impact on a population. A 7.0 magnitude earthquake that would be a devastating disaster in a densely populated and vulnerable city, may be a relatively insignificant geologic occurrence when it strikes an unoccupied island chain. Risk of a disaster is more traditionally calculated by identification of the potential hazard, assess in relation of likelihood of an event as it relates to the potential impact severity – or risk = probability x impact/loss. (Smith 2013). For preparedness, risk formulas are insufficient in the absence of context and consideration for social vulnerability, Birkmann (2007) encourages us to shift away from viewing disasters as large-scale events…show more content…
Initial results of the digital search showed a predominance of earthquake information (90%), very few addressing fire (7%) and even fewer addressing both (3%) Additionally, only 8 % of web and mobile apps allowed for user interaction. (Fagg, Verucci & Rickles 2015). The paper-based advice we reviewed varied widely in quality, detail, and accessibility, but most focused on raising awareness of the hazard and general home based actions for general or single-hazard preparedness specifically; minor acknowledgements of the potential for a subsequent and arising additional hazard (e.g. post-earthquake shut off of gas if there is leak to prevent fire), but none noted the significant link between the two hazards. There is a further leap between the ‘small’ fixes that can be enacted by individuals and those that are more significant or structural changes. These initial findings show a gap that our research might address. Yet, despite all of the information that exists, it has been noted that neither public perception of risk nor perceived knowledge of the hazard and government response arrangements alone are necessarily correlated to preparedness action – either in intention to adopt mitigation measures or in their actual uptake (Lindell & Whitney 2000).
