Landslide inventories for risk assessment in a world heritage site: a case study of Lulworth Cove, UK
Student thesis: Doctoral Thesis
The historical record of landslide occurrence is by far the most important data for assessing landslide risk. The objective of this study is to utilise archive imagery for assessing the probability of landslide occurrence and provide a quantitative landslide risk framework for geo tourism destination in Dorset. Within this study, risk analysis focuses on the risk to loss of life and injury. To calculate landslide risk, landslide inventories were prepared using the analysis of different archive imagery, the spatial and temporal probabilities of potentially damaging events, as well as the visitor exposure, considering also vulnerabilities, were determined. As risk is context-dependant and socially constructed, visitors’ risk perception was also investigated in this study. Results from risk analysis allow for establishing how well the landslides are recorded in the archive sources, to what extent the landslide inventories can be used to determine the frequency of landslide occurrence, and the significance of landslide inventories as a preliminary step for landslide risk assessment.
