Abstract

This report presents the findings of a review of a landslide (Incident No. 2005/10/0554) that occurred on the natural hillside above Beacon Heights, Lung Ping Road, Kowloon. The landslide was reported in the evening of 22 August 2005 following the heavy rainfall on 19 and 20 August 2005.

The landslide involved a failure volume of about 200 m³. Much of the debris was deposited at the toe of the landslide source with a small proportion of the debris travelling into the boulder-filled drainage line below. No casualties were reported as a result of the landslide.

The key objectives of this review were to document the facts about the landslide, including relevant background information and pertinent site observations made under this review. The scope of the review does not include detailed diagnosis of the causes of the incident. Recommendations for follow-up actions are reported separately.
