Report Title : Feasibility Study for QRA of Boulder Fall Hazard in Hong Kong (1998), 61 p.

Author : ERM-Hong Kong, Ltd.


Since 1993, the Geotechnical Engineering Office (GEO) has been assessing the feasibility of applying Quantitative Risk Assessment (QRA) to landslide hazards in the Hong Kong Special Administrative Region. This report presents an evaluation on the feasibility of assessing the risks posed by boulder falls using classical QRA techniques in the Special Administrative Region. In the report, a brief discussion on the factors that could lead to boulder fall initiation has been carried out together with a review of some of the boulder fall incident reports kept by the GEO. The report also includes a literature search on the available international data on risk assessment or hazard analysis of boulder falls. A practical framework and programme for the QRA of boulder fall hazards is also documented.
