12. Risk
The probability of harmful consequences, or expected
losses, resulting from interactions between natural or
human-induced hazards and vulnerable conditions.
Hazard
A potentially damaging physical event
Vulnerability
The conditions determined by factors which increase the
impact of hazards.
Capacity to cope
A combination of all the strengths and resources
available that can reduce the level of risk, or the effects

13. R = risk,
H = frequency or magnitude of hazard,
V = vulnerability level,
C = capacity to cope
