Factors Affecting the Impacts of Geophysical Hazard Events
There are many factors that affect the impact of geophysical hazards, including:
Magnitude and frequency
Location – rural or urban
Population density
Building quality
Time of day
Distance from the hazard event
Geology – rocks and sediment
Level of development
Examiner Tips and Tricks
It is important to recognise that all of these factors are interlinked and may affect one another. For example, level of development affects building quality, and can also affect population density. It is important in the exam that you acknowledge that these factors do not affect the impacts of a hazard event in isolation; it is the combination of all of them that determines the impact that a hazard event has.
