Comparative study of landslide cases in Malaysia: lesson learnt
Landslide events have the devastating impacts on human lives, damage to the physical asset (building, roads and highways), broken of utility supply lines and loss of environmental resources and economic costs. In the period of 59 years from 1961 to 2019, Malaysia has recorded 91 distinct landsl...

Summary: | Landslide events have the devastating impacts on human
lives, damage to the physical asset (building, roads and
highways), broken of utility supply lines and loss of
environmental resources and economic costs. In the period
of 59 years from 1961 to 2019, Malaysia has recorded 91
distinct landslide events which caused 721 deaths.
Urbanization and the high rate of population growth
accelerate the construction of flat ground. In order to cater
to this demand, land utilization becomes more important and
generally shifts toward the hilly area or expands
underground. This paper presents the comparative studies
between 4 landslide cases to come out with the most common
causal factors and rehabilitation methods taken. Studies
showed that landslides occurred in Malaysia is mainly due
to the intense and prolonged rainfall event. Since Malaysia
is experiencing tropical weather, frequent and intense rainfall
event is unavoidable. Therefore, the impact of rainfall shall
be considered and included in the design to minimize the risk
of landslide. Besides, human factors such as deforestation,
design error and construction error should also be reviewed
to effectively prevent the occurrence of the landslide. |
