CAUSES OF LANDSLIDES IN, H.K.:
Landslides are very common in Hong Kong, especially in the rainy summer months. The factors responsible for their occurrence are:
Types of Rocks
Granite is a common rock in Hong Kong and· it is easily subjected to weathering, expe- cially under the moiat and warm climate which encourages active
chemical:weathering. Thick layers of weathered materials. are usually found on slopes. The weathered mantle may have a depth of 200 feet, These loosened materials are very likely to slide down

factors, e.g. heavy rainfall removal of support or weight added above. In some cases, landslides take. place where the more resistant volcanic rocks overlyving. weathered granite. In
these cases, land- slide happen by under- cutting, ive the weathered granite is removed first leaving the volcanie rock'to: slump down.

The uneven.dis− tribution of rainfall is also an important contributing factor. From May to September Hong Kong may be affected by stationary trough which may bring continuous and intensive rainfall. The record of 375-500 mka a day is not surprising. The water soaks into the ground. and may act as a lubricant or destroy. the cohesiveness of soil. All these render the slope unstable. Moreover, the heavy rainwater may add weight to the slope and make the whole mass become more susceptible to down- slope. movement. Structural Condition
The hilly nature of Hong Kong is also favourable factor. The abundance of steep slopes provides an: ideal condition for the occurrence of
landslides..
Vegetation Cover,
Since it has been
believed that vegeti
ation can provide a

protective cover, the scarcity of a hinding
vegetation cover is
considered as a
contributing factor,
too.
Human Activities
Due to the: rapid increase of population and the limited supply. of flat land, high buildings have been. constructed on hill- slopes. It is already accepted that the. existing natural hillside slopes, where made up of colluvial; material, are in state of limiting equili- brium, since they are not the final slopes of these hillsides. Excavation or
of those slopes auto- matically increases the slope angle and this increases the: risk of landslips. PREVENTIVE MEASURES
In an attempt to prevent landsliden the following ways are -suggested;
The Government should. limit intensive development of those. mid-level areas where
the soil is of colluvial origin and: the hillside slopes are in excess of 550 The Government should immediately review its current land policy. with a view to.decent→ ralizing the urban areas and utilizing.. some of the flat land. in the New Territories. for the purpose. This is to be preferred to further exploitation of hilly torrain

should be done before
construction.
Surface drainage channels or conduits can be constructed to drain the water on the slope... In all ground suaceptible to soil: creep, water service mains, particularly
those carrying water under high pressure, should be constructed of materials which are not of brittle nature and thus: particularly liable to fracture arising: from differential movement of the soil。
5. The laying of a layer
of (chunam.plasterior cement. on the surface. of cutting is also effective in preventing large quantity of water from seeping. into the slope..
