The Big Questions
Principal question in studying natural hazards and disasters:
- What hazards exist in an area and which one is under consideration?
When studying any disaster, there are three key questions to ask and one related question:
- How big?
- And the related question -- How often?
And the big question: Is it predictable?
Approaches to Studying Natural Hazards and Disasters
When examining natural hazards, several approaches should be used:
- Science -- what is it, how does it work, in terms of geology, meteorology, physics, chemistry?
- Scientific method -- hypotheses are tested.
- History -- Written, documented record.
- Instrumental record (directly measured record).
- Scientific record.
- Maps and images: when studying natural disasters, a picture often is worth a thousand words!
