About the event

Highlights :

After Tropical Cyclones Lionrock and Kompasu brought torrential rainfall to Hong Kong in early October 2021, a landslide occurred above the natural hillside above Ma Wan New Village, Pa Mei, Tung Chung, Lantau Island. The landslide occurred on an open hillslope with a source volume of about 220 m3. Some of the landslide debris was deposited on the hillside and the remaining debris that travelled further downslope was fully intercepted by a steel flexible barrier (Feature No. 9SE-B/ND12). The principal net of the flexible barrier was bulged but no significant deformation of the barrier structure was observed.

The incident highlights the potential landslide risk arising from progressive deterioration of the natural terrain at the fringes of urban development and that the steel flexible barrier designed and constructed under the LPMitP was effective in intercepting the landslide debris and preventing it from reaching the toe facilities.
