EFFECTS AND LOSSES DUE TO LANDSLIDES

A) Direct Effects:

• Physical Damage-Debris may block roads, supply lines (telecommunication, electricity, water, etc.) and waterways.

• Causalities- deaths and injuries to people and animals.

B) Indirect Effects:

• Influence of landslides in dam safety- failure of the slopes bordering the reservoir, Flooding caused by movements of large masses of soil into the reservoir.

• Landslides and flooding- Debris flow can cause flooding by blocking valleys and stream channels, forcing large amounts of water to backup causing backup/ flash flood.

HOW TO MINIMIZE LANDSLIDE HAZARDS

A) Passive Intervention

• Choose a safe location to build your home, away from steep

slopes and places where landslides have occurred in the past.

• Prevent deforestation and vegetation removal.

• Avoid weakening the slope.

B) Active Preventive Intervention

• Reforestation: Root systems bind materials together and plants

do both prevent water percolation and take water up out of the

slope.

• Proper water runoff must be ensured by providing a proper

canalization network.

• Drainage: good ground drainage is essential to prevent

saturation and consequent weakening. Drainage is also needed

in civil work, like retaining walls.

LANDSLIDE PREPAREDNESS AND SAFETY MEASURES

A) Before a landslide:

• Find out landslides have happened in your area in the past.

• Look out for landslide warning signs like doors or windows

jammed for the first time, new cracks appear in walls,

bricks, foundations, retaining walls, tilt of utility poles or

trees.

• Consider relocation in case your house is located in an area

particularly vulnerable to landslides. While doing so,

remember:

i) Do not build on or at the base of unstable slopes, on or at

the base of minor drainage hollows, at the base or on top

of an old fill slope, at the base or top of a steep cut slope.

• Innovative site specific measures

• Slope reduction

• Retention Structures

• Fluid removal

• Other slope stabilizing method

• Recognizing the hazard

• Landslide Warnings

• Slope Safety Audit

PREVENTIVE MEASURES

APPROACH NEEDED

�Develop/introduce good practices for early warning of landslides.

�Form joint working groups with representatives of landslide professionals to analyse the critical factors responsible for destabilisation of slopes.

�Introduce and develop existing as well as new concepts pertaining to precipitation threshold values for landslide initiation in different geological materials.

�Provide input to national and regional multi-hazard platforms for early warning and propose suitable preparedness measures to suit respective areas

IMPORTANT FACTORS FOR LANDSLIDE EARLY WARNING

• Experience (success stories)on implementation

and operation of a landslide early warning

system

• How data gathering can be done in target Area

for developing a rainfall-landslide trigger

relationship

• Institutional set-up for early warning

• Monitoring and predicting

• Communicating alerts to at risk communities

• Response plans at various levels

WHAT FEATURES THAT MIGHT BE NOTICED BEFORE MAJOR

LANDSLIDES

� Springs, seeps, or saturated ground in areas that

have not typically been wet before

� New cracks or unusual bulges in the ground, street

pavements or sidewalks

� Soil moving away from foundations

� Ancillary structures such as decks and patios

tilting and/or moving relative to the main house

� Tilting or cracking of concrete floors and

foundations

� Broken water lines and other underground

utilities

WHAT FEATURES THAT MIGHT BE NOTICED BEFORE MAJOR

LANDSLIDES

� Leaning telephone poles, trees, retaining walls

or fences

� Offset fence lines

� Sunken or down-dropped road beds

� Sudden decrease in creek water levels though

rain is still falling or just recently stopped.

� Sticking doors and windows, and visible open

spaces indicating jambs and

� frames out of plumb

10/24/2019

7

� Risk of disaster can be minimised if we follow the points

/remedies indicated in above slides. Spread awareness

among masses

� Scientific development of hill area’s is need hour

� Public and States required to support DRR efforts.
