Landslides occur in different forms, from individual rock falls to large creep failures depending on site conditions and the type of the triggering event (earthquake, precipitation, erosion, excavation, etc.). Based on their characteristics (number, timing, location, size, mobility, etc.), landslides can have significant consequences such as casualties, property damage or socioeconomic impacts, which constitute the 'hazard' and the 'vulnerability' of people, structures and infrastructure that exist or live in the potentially affected area. Such undesirable impacts can be prevented or reduced through various actions using 'efficient' mitigation strategy, such that presented in this paper. The objective for any site or set of sites should be to identify and implement those actions, which are most cost-effective amongst the alternatives. A prioritisation policy of the susceptible landslides areas that can primary or secondary affect human lives and economy can be applied as a result of the proposed landslide risk assessment methodology.
