Asian Program for
Regional Capacity Enhancement for Landslide
Impact Mitigation (RECLAIM)
Landslide Mitigation
Demonstration Project in Thailand
Introduction
Landslide is considered to be a high-risk
hazard in Thailand since limited risk
management has been done. This study efforts
to provide better understanding of the
causative factors and mechanics of the
landslide and select vulnerable location for
implementation of
a Landslide Mitigation Demonstration Project
in Thailand. Landslide mitigation
works are conducted in order to stop or
reduce the landslide movement so that the
resulting damages can be minimized.
In
Thailand, the landslide hazard happens
almost every year and causes economic
damages and deaths. Records of landslide
since 1970 show that landslides occur
increasingly every year. This can be
explained by two reasons: natural phenomenon
and mismanaged land use. In August 2006, a
large landslide happened in Trait province
of Thailand. That single event alone caused
83 lives and cost and damages of about 308
million baht. Appropriate land management
could have saved many lives.
Identification of the Landslide Problem on
Phuket island
Department of Mineral Resources in collaboration with
Geotechnical Engineering Research and
Development Center (GERD), Kasetsart
University is developing a landslide hazard
map in 6 provinces affected by Tsunami. This
landslide hazard zonation is undertaken to
manage the land properly after the 2004
tsunami incident. The study was done in 6
provinces including Ranong, Phang-nga, Krabi,
Trang, Stun and Phuket. Landslide risk
prioritization has been done and the results
show that Phuket city is the most risky area
among the study area, because Phuket island
is formed by granitic and mudstone rocks
that have a high potential of sliding. The
existing landslide areas were investigated
in order to collect the data for various
(Fig 1, 2 and Fig 3).
Description of the selected study area (Patong)
Patong city is situated on the west coast of Phuket Island.
The city stays in an embayment surrounded by
high altitude mountainous range. Population
in the city consists of tourists and local
Muslims people. The city has a limited
plain area for development. After the
tsunami incident, land developers attempt to
build the buildings in the upper level of
the mountain, and thus disturbing the stable
slope. Landslide is then easily triggered
by the changing of landforms and destroying
the land cover. Proper action needs to be
done in order to prevent a potential large
landslide in the city.
Objectives
-
To demonstrate implementation of a
landslide mitigation project.
-
To determine the landslide acceptable
risk of Patong area.
-
To develop guideline for
monitoring/warning system.To campaign with information material about landslide
hazard warning concept, awareness for
the city.
