Abstract

This report presents the findings of a review of a landslide (Incident No. 2006/07/0672) that occurred on 16 July 2006 on slope No. 14NE-B/CR180, above a village house at No. 49 Po Wah Yuen, Yung Shue Wan on Lamma Island. The failure involved a shallow landslide in the soil cut slope with an estimated debris volume of about 15 m³, which was deposited on the level ground at the slope toe. Muddy water associated with the debris mound was reported to have entered the dwelling through the gap at the base of the rear door. No casualties were reported as a result of the incident.

The key objectives of the review were to document the facts about the incident, the site history and pertinent observations. The scope of the review does not include any ground investigation or detailed diagnosis of the causes of the incident. Recommendations for follow-up actions are reported separately.
