Abstract:
An earthquake commonly triggers widespread and destructive damages, which these
can include building collapse, tsunami, liquefaction, and landslide. The
earthquake that struck the western region of Sabah on June 5th, 2015, with a
local magnitude of 5.9, induced severe and extensive land instabilities in
areas such as Ranau, Tambunan, Tuaran, Kota Kinabalu, and Kota Belud.
Unfortunately, there is only a very limited literature on earthquake induced
landslides in Malaysia. Therefore, the aim of this study is to understand the
mechanism of earthquake induced landslide at Sekolah Menengah Kebangsaan (SMK)
Ranau using 2D finite element method in RS2. The displacement measured from the
slope at SMK Ranau is used to verify the model and the effect of the seismic
load has been monitored. A good agreement was found between the numerical model
and actual site condition. In depth understanding of earthquake triggered slope
failure was successfully studied using the RS2 software.
