GEO Shorts: Landslide on the Natural Hillside above Ma Wan New Village, Lantau Island.

The western half of Lantau Island of Hong Kong is composed primarily of Jurassic Tuff and Lava. Landslides are common in this area due to undulating rockhead levels and weathering profile of extrusive felsic igneous rocks. Moreover, in rainy periods, its dense subtropical forests are excellent water catchments, which builds up pore pressures, decreasing the effective stress and apparent friction angle of the rock/soil interface. Despite its dangers, urban settlements are littered around such hillsides in west Lantau. The Geotechnical Engineering Office (GEO) of the Civil Engineering and Development Department (CEDD) of the Government of Hong Kong SAR, through the Landslip Prevention and Mitigation Program (LPMitP), has appointed ARUP to assess and mitigate slope hazards of the Pa Mei area in Tung Chung circa 2008. <a href="https://medium.com/@calebbsang/geo-shorts-landslide-on-the-natural-hillside-above-ma-wan-new-village-lantau-island-cf0e1cec1169">Learn More</a>
