Abstract

This report presents the findings of a review of a landslide (Incident No. 2006/06/0623) that occurred on slope No. 7NE-D/FR58 along Ma On Shan Tsuen Road on 2 June 2006 when the Landslip Warning and the Red Rainstorm Warning were in effect. The landslide involved the failure of a masonry wall and the fill slope above. The detached debris, with a volume of about 350 m³, blocked Ma On Shan Tsuen Road, a sole access to Ma On Shan Tsuen, causing temporary closure of the road. No casualties were reported as a result of the incident.

The key objectives of the review were to document the facts about the landslide, present relevant background information and pertinent site observations made under this review. 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.
