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

Objectives Establishing an International Standard for the implementation of

landslide EWS, by Integrating technical and social networks

Reducing risk from landslide disasters by increasing the

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

4 key element for community-

based EWS (UN-ISDR, 2006)

Concept of Hybrid Socio-Technical System

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.

15

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.

17

Establishment of disaster preparedness and

response team In charge of determining landslide risk zones and evacuation routes

and mobilizing people to evacuate before the landslide occur.

Responsible for operating and maintaining monitoring tools

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.

Description:

1. Title indicating the location of theLEWS implementation;

2. Logo of the local authorities or otherrelevant stakeholders

3. Evacuation map and routes;

4. Legend and important information(landmarks) including common signseasily recognizable;

5. Name of the heads of the families.

NOTE: The evacuation map does notneed to include the scale, but only thenorth direction that can be placed in thelegend. The north direction may not faceup, depending on the local customs.

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.

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.
