Landslide
A landslide or landslip are a natural disaster, something
which is unfortunately unavoidable. Landslides can vary in size but usually
they always involve a large ground movement. This can be things such as debris
and rock failing. A landslide can occur on shore or off shore and usually
at coastal lines but it is the gravity that forces the debris and rocks to fall
and for a total landslide to occur.
If an area has some pre conditional factors, it could help
to build up a lot of problems, sub surface problems and conditions from
arising. The conditions could make the slope to continuously product
landslides.
The Causes of a landslide :
Ø Erosion
– if this occurs, even just slightly, can make some of the slope to fall in to
oceans or rivers.
Ø Glaciers
can also have a landslide – there is not much of a different from a cliff
top. Instead, the ice melts or is subject to heavy rain and causes a
slight shift from a glacier.
Ø Earthquakes
– this brings about a sharp change in the slope and makes it unstable.
Ø Groundwater
can destabilize the slope putting pressure on it greatly.
Ø Volcanoes
erupting – this can cause the slope to become unstable.
Ø Soil
structure can change.
However, these are all natural
causes for a landslide to occur but human activities can contribute to cause a
landslide.
Ø Heavy
machine vibrations in the ground
Ø Deforestation
can make fragile slopes unstable.
