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.
