WHAT IS A LANDSLIDE ?
It is a down slope transport of soil and rock resulting from
naturally occurring vibrations, changes in direct water content,
removal of lateral support, loading with weight, and weathering
or human manipulation of water course and slope composition.
Landslides vary in
types of movement (falls, slides, topples, lateral spread, flows)
and may be secondary effects of heavy storms, earthquakes, and
volcanic eruptions. Landslides are more widespread than any other
Anything on top
of or in the path of a Landslide will suffer damage
Rubble may block
roads, lines of communication or waterways. Indirect effect
may include loss of productivity of agricultural or forest
values, destruction of buildings.
may occur due to slope failure.
CONTRIBUTING TO VULNERABILITY
on steep slopes, softer soils and cliff tops
at the base of steep slopes, on mouths of streams from mountain
lines in mountain areas
and brittle pipes.
Lack of understanding
of landslide hazard
Community Education after identification of areas most at risk
from landslides. The basic information required:
where past Landslides have occurred, derived from local records
and knowledge of certain types of rocks prone to landslides.
and evacuation systems
Capture and drainage
of water before it reaches potential slope area
by using sub-surface pipes
Land Reform by
planting of deep rooting trees to prevent surface slips
with grass or agricultural crops
