What impact do mudslides have on the environment?

Mudslides move at more than 20 mph and contain not just mud, but rocks, trees and other debris. This means they can rip land to pieces, leaving deep gullies and large mud deposits. Mudslides can devastate agricultural land: all crops will be destroyed.

What are the impacts of landslides?

The impact of a landslide can be extensive, including loss of life, destruction of infrastructure, damage to land and loss of natural resources. Landslide material can also block rivers and increase the risk of floods.

How does deforestation speed up landslide?

Deforestation generally increases rates of soil-erosion, by increasing the amount of runoff and reducing the protection of the soil from tree litter. Trees removal on steep slopes with shallow soil thus increases the risk of landslides, which can threaten people living nearby.

Why deforestation is the main cause of landslide?

This happens mainly because roots help fix trees in the ground and the sun-blocking tree cover helps the soil to slowly dry out. As a result, deforestation will probably mean the soil will become increasingly fragile, leaving the area more vulnerable to natural disasters such as landslides and floods.

How does changing the natural drainage trigger landslides?

Irrigation alters natural surface drainage. Surface run- off of irrigated water on slopes exposes soil under cultivation to erosion. Part of this water is absorbed by soil increasing its weight, which can put an additional load on the slope.

What should we do when landslide occurs?

What To Do After a Landslide

  1. Stay away from the slide area.
  2. Listen to local radio or television stations for the latest emergency information.
  3. Watch for flooding, which may occur after a landslide or debris flow.
  4. Check for injured and trapped persons near the slide, without entering the direct slide area.

How can I protect my house from a landslide?

Protect your property by planting ground cover on slopes and building retaining walls. 6. In mudflow areas, build channels or deflection walls to direct the flow around buildings. Be aware, however, if you build walls to divert debris flow and the flow lands on a neighbor’s property, you may be liable for damages.

What is the purpose of a family emergency plan?

The Family Emergency Plan is a useful tool that can assist householders and family members in advance planning exercises. It forms part of any preparedness strategy and as a result may go a long way in preserving human life, limb and property before, during and after a hazard impact.

How can you practically cope with the hazards?

  1. Check yourself for injuries.
  2. Help injured or trapped persons if you can.
  3. Be prepared for aftershocks.
  4. Clean up spilled medicines, bleaches, and gasoline immediately.
  5. Open cabinet doors cautiously.
  6. Listen to the radio or television for more information from authorities.
  7. Stay out of damaged buildings.

How can a disaster affect the future of a community?

Disasters may be explosions, earthquakes, floods, hurricanes, tornados, or fires. In a disaster, you face the danger of death or physical injury. You may also lose your home, possessions, and community. Such stressors place you at risk for emotional and physical health problems.

How can we reduce the impact of disasters?

Awareness, education, preparedness, and prediction and warning systems can reduce the disruptive impacts of a natural disaster on communities. Mitigation measures such as adoption of zoning, land-use practices, and building codes are needed, however, to prevent or reduce actual damage from hazards.
