hazards and disasters Flashcards
(30 cards)
define a hazard
situations with a potential to cause harm to people and/or the environment. i.e tectonic movement in japan
define a hazard event
when a hazard is realised (the event actually occurs)
define a disaster
a sudden calamitous event that seriously disrupts the functioning of a community or society and causes human, material and economic or environmental loses that exceed the community’s or society’s ability to cope using its own resources
define geological or geophysical hazard
hazards associated with the dynamics or plate tectonics volcanic activity, earthquakes and tsunamis, landslides, avalanches
define hydro-meteorological or atmospheric and climatalogical
wide range of hazards including drought, flood, storm, bushfires
define biological hazards
those associated with forms and their processes e.g. infectious diseases such as covid, HIV/ AIDS
define technological hazard
there origins are connected to human activity they often combine with natural processes to produce hazards e.g. oil spills, air pollution, acid rain, industrial waste
what are the hazard speeds
Rapid onset
slow onset
define rapid onset
very quick
high risk
define slow onset
months or years lower risk
define frequency
the more significant the less frequent
compound disaster
one disaster creates another
Fatalistic
people accept hazard events as unavoidable
may be due to lack of education and understanding of the potential risks or thinking that the hazard will not impact them greatly
acceptance
people who believe that the benefit of living in a certain hazard prone area outweighs the potential hazard and its effects
Adaption
people who live in a hazard prone areas but are well prepared for any event
situations with a potential to cause harm to people and/or the environment.
