In fact, the major characteristic of a risk is mainly given by the importance of the damage which it is likely to generate: Vulnerability of a zone or a given point is the appreciation of the sensitivity of the targets present in the zone at a type of effect given (intensity of seism, volume of precipitations, concentration of toxic product, etc.). ), infrastructures (gas/water/electricity supply networks, road, etc.), cultures (agricultural, animal, etc.), and naturally population. Stakes are buildings (commercial dwellings, buildings, factory sites. Risk is the probability that an accidental phenomenon produces in a given point of the effects of a given potential gravity, during one given period. Hazard is characterized by its probability of realization (annual, decennial, centennial.) and its intensity (magnitude for seisms, height and speed of water for floods, bandwidth for landslides, etc.). Hazard, risk, stakes, vulnerability: what is the difference? Consequently, a potentially dangerous event, the HAZARD, is not transformed into RISK only if it applies to a zone where human, economic or environmental STAKES are in presence and this zone has a certain degree of VULNERABILITY.
