What is landslide?• Down-slope movement of soil, rock and debris or

earth under the influence of gravity, and also the land form that result

Causes of Landslides• Natural causes • Man-made causes

Landslide Impacts

Direct ImpactPhysical DamageDebris may block roads, supply lines (telecommunication, electricity, water, etc.), and water-ways.CasualtiesDeath and injury to people and animals.Indirect lossesLoss of productivity of agricultural and forest land, flooding.

Indirect Impacts

• Disruptions or hindrances of the economic activities• Interruption of the traffic• Reduction of tourist demand(These indirect impacts are difficult to assess.)

Where do landslide Usually Occur?

• Associated with hilly or mountain landscapes.• Also common allow coastlines and river valleys.• Landslide occur in most frequently in region where

climate and precipitation, bedrock and soil condition, and slopes are susceptible to failure.

How to recognize Landslide Warning Sign?• New cracks appear in plaster, tile, brick, or foundation.

• Sudden appearance and rapid expansion of cracks on road pavements or ground surface.

• Outside walls, walks, or stairs being pulling away from the building.

• Sudden breakage of water supply lines and other underground installations and underground utility lines.

May 2, 2023 19

• Sudden appearance and disappearance of creeks.• A faint rumbling sound that increases in volume become

noticeable as the landslide nears.• Bulging ground appears at the base of a slope.• Fences, retaining walls, utility poles, or trees tilt or move.• Rapid increase in water levels in pools, steams, etc. in

mountainous areas.

General guidelines for those living in a landslide-prone areaFor normal time• Do not built near slopes, close to mountain edges.• Minimize home hazards.• Plant ground cover on slopes and building retaining walls.• Have flexible pipe fitting installing to avoid gas or water

leaks.• In mudflow areas, building channels or deflection walls to

direct flow around buildings.• Listen to weather forecasts.• Remain awake during nights of heavy continuous rain and be

ready to move to a safer location.

May 2, 2023 22

• Observe the warnings signs mentioned and inform the authorities when such warning signs are recognized.

• Listen for abnormal sounds of soil and rock movement or breaking of trees.

• Observe abnormal behavior of domestic animals.• Never go closer to observe cracks on the slope.

Prior to a Potential Landslide

• Stay alert and stay awake.• If you are in areas susceptible to landslides and debris

flows, consider leaving if it is safe to do so.• Contact your local authority, village disaster

committee, fire services department, or police force.• Especially be alert when driving.• In case need to evacuate, do so immediately.• While evacuating, do not cross possible landslide paths.

May 2, 2023 24

• When see falling rocks, seek cover behind trees and other solid objects.

• Inform affected neighbors.• Evacuate. Getting out of the path of a landslide is best

protection.

May 2, 2023 25

During a Landslide• Quickly move.• If escape is not possible, curl into a tight ball and protect head.

After a Landslide• Stay away from the slide area.• Check for injury and trapped persons near the slide, without

entering the direct slide area.

May 2, 2023 26

• Listen local radio or television stations for the latest emergency information.

• Watch for flooding.• Check the building foundation.• Replant damaged ground as soon as possible.

Community-base Organization on

Disaster Management Plan(CBDMP)

• Education and awareness generation• Community-based landslide risk assessment• Landslide monitoring and warning system• Landslide preparedness at the household level• Family Landslide Preparedness Plan
