0001 Generally speaking, slope failures and landslides are mainly caused by heavy rainfall, water/sewer pipe leakage. Water saturation and high pore water pressure weaken the bonds within the rock & soil masses of the slopes (cut slopes, fill slopes, slopes behind all kinds of retaining walls), causing failures. (March 5, 2016)

0002 High-intensity rainfall of short duration is a major triggering factor for landslides (March 5, 2016).

0003 Definition of Landslide: The movement of a mass of rock, debris, or earth down a slope (March 5, 2016).

0004 In Hong Kong, the wet season (and co-incidentally the most frequent typhoon period) includes second half of May, June, July, August, and September. According to the reports made by the Water Supplies Department, the amount of rainfall during these 4+ months is almost 10 times the total amount of the remaining year. As a result, slope failures and landslides are more likely to occur during the wet season. On the other hand, repair and construction works are best to be done in advance of or after the wet seasons. (March 5, 2016)

0006 Minerals are fundamental components of rocks. They are made up natually with inorganic substances, of specific chemical comprositions, and of orderly repeatative actomic structure. Fundamental crystal structure. (from ISBN: 978-962-02-0381-7) (March 15, 2016)

0007 Silicate minerals are the most abundant components of rocks on Earth's surface. Making up over 90% of Earth's crust. The building blocks are silicon tretroxide, SiO4. . The remaining 10% includes carbonate, oxides, sulphides, phosphates, and chlorides. A few elements may occur in pure form, these include gold, silver, copper, bismuth, arsenic, lead, tellurium and carbon. (from ISBN: 978-962-02-0381-7) (March 15, 2016)
