Economic Impact Assessment of Landslide Events

The economic impacts of landslide events can be classified into those that are direct, direct consequential and indirect consequential. In this paper we present data from a set of four landslide events/groups of events, that occurred in Scotland in 2004 and 2007, on the first two impact types and indicate progress on work to develop the methodology for and data gathering on the third type. The data presented here relates to events that occurred in a road environment and for which there were no casualties. Direct costs range between approximately £300 k and £1,400 k whereas direct consequential costs range between around £100 k and £1,000 k. The latter costs are largely dependent upon the amount of traffic that uses the road and the duration of the disruption that is caused by the landslide event(s).
