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