Background It is difficult to relocate community (peoples) living in landslide
vulnerable area. The most effective DRR effort is to improve
the community’s preparedness by implementing EWS.
Warning system which mainly emphasize on technical
approach mostly does not work properly due to lack of
community awareness with result in poor maintainance and
operation.
Improve community preparedness and willingness to protect
themselves from landslide disasters.
Integration of technical and social system is required to support
the community empowerment program for DRR in landslide
vulnerable area.

Background (cont.)
EWS implementation in the world is in line with the 2015-2030
Sendai Framework for Action with four (4) priorities in DRR :
“The improvement of preparedness
in order to respond effectively to a
disaster, by implementing a simple,
low-cost EWS and improving the
dissemination of information about
EWS of natural disasters at local and
national levels.”
Referring to the four key elements of community-based EWS (UN-
ISDR, 2006), therefore it is necessary to develop a standardization
for landslide EWS
1. Understand disaster risk
2. Strengthen disaster risk
governance to manage
disaster risk
3. Invest in DRR for resilience
4. Invest in disaster
preparedness to enhance
response

community awareness – preparedness - resilience
Community empowerment with respect to community-based
disaster risk reduction in landslide vulnerable area
Users International organization/institution
Central and local government authority
Private sectors, NGOs
Local community

Concept of Hybrid Socio-Technical System
![Page 14: ISO 22327: Guidelines for implementation of a community ....

Risk Assessment• Technical survey on geological
conditions to determine landslide
susceptibility and stable zones.
• Institutional survey to understand
whether an established institution
exist to monitor and mitigate
landslide hazards in the disaster-
prone areas.
• Social survey to understand the
community’s understanding of
landslide hazards.

Landslide hazard mapping by the community

Dissemination• Methods and materials of the
dissemination are tailored based
on the preliminary data of the risk
assessments
• The community could understand
the landslide mechanisms,
symptoms, and how to minimize
risks
• Identifying the key people who
have a strong commitment as
forerunners in the establishment of
disaster preparedness team.

Development of evacuation routes and maps
The evacuation map should provide the information on: • High-risk and low-risk (safe) zones;
• Residences, including the estimation of the number of residence
in each;
• Community facilities: school, place of worship, community health
centre, offices, market and landmarks;
• Streets and alleys;
• Locations of early warning system installation point;
• Alert post;
• Assembly Point(s);
• Evacuation route(s);
• Location of shelters.
Maps need to be made simply so that it is easier to
understand by the local community.

Development of Standard Operating Procedure
The SOP contains the procedures for responses by the
disaster preparedness team and the community to the alert
issued by the landslide early warning instrument.
The SOP was prepared based on the discussions and
agreements of each division under the direction of relevant
stakeholders to follow the flow of warning information delivery
mechanism and evacuation commands.
![Page 21: ISO 22327: Guidelines for implementation of a community ....

LEVEL 1: CAUTIONTriggered by rain gauge sensor. The disaster experts should determine
the critical limit for rainfall intensity that may trigger landslide in mm/hour
or mm/day. If the critical limit is exceeded, then the device will give
CAUTION warning.
LEVEL 2: WARNING Triggered by tiltmeter. Disaster experts should determine the critical limit
of soil movement in degree (°)/minute or per hour, in the X-Y direction (N-
S and W-E). If the instrument indicates slope inclination change that
exceeds the critical limit, it will trigger the WARNING warning mechanism.
Vulnerable groups should be evacuated first.
LEVEL 3: EVACUATE Triggered by extensometer. This device has critical limit in mm/minutes or
mm/hour, depending on the field condition determined by the disaster
experts. If the movement exceeds the critical limit, the device will trigger
the EVACUATE warning mechanism.

Monitoring, Early Warning, and Evacuation Drill
• Determination of the locations is based on the identification of
landslide risk zones. Installation of the equipment is done with
the community, aiming to increase the sense of ownership and
responsibility for the equipment’s condition to guarantee safety.

Commitment of the local government and
community on the O&M of the systems
The commitment of the local government and the community
is crucial in the operation and maintenance of the early
warning system, so that all activity stages included in the
SOP run well.
The duty and responsibility in terms of ownership,
installation, operation, maintenance, and security of an early
warning system are adjusted to the condition in each location
and are agreed upon by the government, the community, and
the private sector.
