hazard profiles Flashcards
what are hazard profiles?
a diagram that shows multiple characteristics of different hazards
- help governments develop disaster plans (e.g. warnings, drills, and evacuations)
- compares and contrasts different hazards
- helps decision makers to identify and rank hazards
- typical earthquake and volcano profiles tend to differ most in terms of spatial predictability and frequency
what are the limitations of hazard profiles?
- difficult to compare hazards
- different impacts on society
- varying spatial and temporal distributions
- to accurately rank hazards on one scale, some key elements may be inaccurately displayed or omitted
what are some characteristics of hazard profiles?
- magnitude
- speed of onset
- duration
- areal extent
- spatial predictability
- frequency
