NEC Successfully Trials Landslide Prediction System in Thailand

NEC Corporation (TSE:6701), in collaboration with Thailand's
National Disaster Warning Center (NDWC), announced today the
completion of a trial for a system that identifies areas where
there is danger of a landslide occurring. The effectiveness of the
system was confirmed as the trial was conducted in Chiang Mai
Province in Northern Thailand during the period from November 2016
to March 2017.
Landslides caused by heavy rainfall are frequent in Thailand, and
they result in personal injury and damage to property as well as
affecting transportation by destruction of roads. For those
reasons, measures for reducing such damage are urgently needed.
In April 2015, Japan's Ministry of Internal Affairs and
Communications and Thailand's Ministry of Information and
Communication Technology(1) issued a joint statement announcing
that the two countries would cooperate in a wide range of areas,
including the development of more sophisticated disaster prevention
ICT and the use and application of the technologies. As a country
that experiences frequent natural disasters, Japan is expected to
contribute to disaster prevention in Thailand through provision of
its advanced technologies.
This trial supports the disaster prevention cooperation project
between Thailand and Japan. NEC conducted this trial in
collaboration with the Embassy of Japan in Thailand as part of the
"Research and study for the development of a landslide simulator in
Thailand" project commissioned by Japan's Ministry of Internal
Affairs and Communications.
NEC joined NDWC(2) in conducting verification experiments with a
flooding simulation system in Uttaradit Province in Northern
Thailand between November 2015 and March 2016. The trial reported
here is a follow-up to that work.
The landslide prediction system is one of the modules of NEC's
"integrated risk management system." The integrated risk management
system consists of a shared platform that has functions such as
data integration, visualization, and early warning, and disaster
modules specialized for particular disasters such as landslides,
flooding, and earthquakes. The disaster modules or functions can be
selected individually as required, or several disaster modules can
be combined in order to predict multiple disasters
simultaneously.
The landslide prediction system performs a simulation based on
meteorological data (observed rainfall and forecast rainfall),
topographical data (elevation values, land use purposes), and soil
data (soil depth, hydraulic conductivity, porosity, cohesion force,
internal friction angle, etc.), making it possible to predict the
degree of landslide danger.
Further, the system can perform detailed simulations using a 50-m
quadrilateral mesh and provide hourly-basis prediction for a period
of up to seven days in advance. This allows NDWC to issue warnings
to threatened areas before the landslides occur, helping to reduce
potential damage. Moreover, even during periods when no disaster is
forecast, areas at risk of landslides can be identified by
performing simulations using previous rainfall data, which enables
hazard maps to be prepared.
"We were able to construct the NEC landslide simulation system in
cooperation with various Thai government organizations. The system
is optimized for Thailand and is expected to have a role in the
operations of the Department of Disaster Prevention and Mitigation
and the NDWC," said RADM Thavorn Charoendee, Executive Expert,
National Disaster Warning Center. "With the ongoing cooperation of
Japan, the Thai government will continue to expand the simulation
area."
"NEC will continue to contribute to the development of more
sophisticated disaster prevention ICT and the use and application
of the technology for preventing disasters in Thailand, such as
landslides and flooding," said Minoru Hirata, General Manager,
Smart Infrastructure Division, NEC Corporation. "Further, we will
harness the experience and knowhow gained through this trial to
actively promote the system to other countries in Asia that
experience frequent damage from landslides."
