Quantitative Risk Assessment

Risk Analysis – General Equation

Annual probability of a landslide could cause fatality, f:

f = P x P x P ST
L
TL
where,

• P is the frequency of landsliding (occurrence/year)
L

• P is the probability of the landslide reaching the
TL
element at risk (depends on travel distance)

• P is the spatial and temporal probability of the person
ST
at risk (to be at the wrong place at the wrong time)
