What Can you do to prevent landslides?

Answer 1

Landslides cannot be prevented 100% of the time. However, their scope and severity can be reduced by not building human structures at the base of steep hills andmaintaining native ground cover (plants such as grasses) on hills.

Answer 2

Landslides generally happen where they have occurred in the past, and in identifiable

hazard locations. Areas that are prone to landslides include existing old landslides, the

bases of steep slopes, the bases of drainage channels, and developed hillsides where

leach-field septic systems are used.

Areas that are typically considered safe from landslides include areas that have not

moved in the past; relatively flat areas away from sudden changes in slope; and areas at

the top of or along ridges, but set back from the edge of slopes.

People can reduce their personal risk by learning about potential local landslide hazards

and taking steps to reduce those hazards.

Landslides are usually isolated events occurring without public warning. If you live in a

landslide-prone area, be alert, particularly during periods of heavy rainfall or snowmelt or

after a wildfire. If you see signs of a landslide or suspect a landslide may occur, you

yourself must make the decision to evacuate.

There are a number of potential solutions which are used to try and prevent a landslide occurring in soil slopes which commonly involve either increasing the strength of the soil mass or reducing the stress acting upon it.

Soil nailing is a process whereby steel bars are grouted into holes drilled into the unstable soil slope face. These are placed in a regular array and act to reinforce the soil by increasing it's tensile and shear strength.

Mini piling is similar in concept to soil nailing however the piles are commonly of higher strength and larger dimensions than a soil nail and so would be used in situations where a greater restraining force is required to support the soil mass but also require more extensive and expensive works to place.

Other solutions include lime stabilisation which involves boring columnar holes into the soil and mixing a lime or other grouting material into the fill material which acts to increase the soil strength, inhibiting the formation of shear planes and halting soil movement.

Another solution may be de-watering which is a process where the groundwater table is lowered. This acts to reduce the pore water pressure in the soil mass in turn increasing the in-situ stress and hence the shear strength of the soil which can halt movement.

Another potential solution is the planting of vegetation on the soil slope whereby the roots will act to bind the soil mass increasing it's strength and acting to inhibit the formation of shear surfaces which are necessary for slope failures / movements to occur in soils. Vegetation will also act to reduce the infiltration rate of water into the soil which can reduce the fluctuations in pore water pressure which will also act to increase the stability of the soil slope.

Since a landslide can happen any time, make sure you know these landslide safety factsAnyone who's spent time in the mountains can appreciate the beautiful scenery that accompanies them; however, that scenery also comes with the potential for hazardous landslide disasters.

Following these landslide prevention tips can help protect your family, your property and yourself.

For your homeThe best time to make sure your home is stable for landslides is when you're remodeling. Consider taking steps to help with landslide prevention:

• Don't build steep slopes close to mountain edges, near drainage ways or natural erosion valleys
• Install flexible pipe fittings to avoid gas or water leaks
• Plant ground cover on slopes and build retaining walls
• Build channels to redirect mudflow
• Get a ground assessment and landslide history of your property

For your safetyTake caution if you see these warning signs of a landslide disaster in your area:

• Changes occurring in your landscape such as land movement, small slides, flows or progressively leaning trees
• Doors or windows that stick or jam for the first time
• New cracks that appear in plaster, tile or foundations, or outside walls, walks or stairs that begin pulling away from the building
• Slowly developing but widening cracks that appear in roads and sidewalks
• Bulging ground that appears at the base of a slope
• Water that breaks through the ground in new locations
• A faint rumbling sound that increases in volume
• Unusual sounds such as trees cracking or boulders knocking together

If it is safe to leave the area, do so; otherwise move to the highest level of your house, curl into a tight ball and protect your head.

This landslide safety information is meant to help you make decisions that may reduce your risk. Of course, we can't note every possible risk, and we can't guarantee that these tips will work for you. However, we hope that if you use some of them, you'll better protect your family and yourself.

Answer 5

don't cut trees down(don't cause deforestation)

trees hold the soil firm so if we cut the trees, the soils get loosen

Answer 6

Yes the root system of trees help hold soil together. This can help prevent landslides.

Answer 7

plant trees yearly because roots of tress hold the soil that could prevent landslide
