The Geotechnical Engineering Office of Hong Kong database of landslides for the period 1984-1993, containing over 3000 landslide records, and data for major landslides before this period were made available for a landslide risk assessment study. Data from over 1100 of these landslides in man-modified slopes were collated, processed, and analyzed statistically. Multiple regression models, based on slope geometry, were developed for the prediction of landslide travel on a horizontal surface below the slope. Although developed for slopes in Hong Kong, the models can be applied in similar geological situations (weathered granite and other weathered volcanics) and are suited for landslide risk zoning in areas below man-modified slopes and for the assessment of risks from individual cuts and fills.Key words: landslide, travel distance, risk, risk assessment.

Landslides are unavoidably linked to forestry operations in coastal BC. A neglected component of landslide risk assessment is the degree to which impacts from landslides may be acceptable. One hundred and thirteen professionals in the BC forest industry, including foresters, biologists, geoscientists and engineers, examined landslide tolerability criteria. Despite differences by sector, there was general agreement that landslides resultant of ignoring expert advice or where an expert was clearly at fault were unacceptable, and penalties were high. In more ambiguous cases, increased consequences resulted in increased scrutiny and it was clear that experts should expect to be held responsible for their decisions by government officiators and the public. Key words: landslide, risk, risk perception, acceptable risk, landslides and forestry
