A landslide or landslip is a geological phenomenon which includes a wide range of ground movement, such as rockfalls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. Although the action of gravity is the primary driving force for a landslide to occur, there are other contributing factors affecting the original slope stability. Typically, pre-conditional factors build up specific sub-surface conditions that make the area/slope prone to failure, whereas the actual landslide often requires a trigger before being released.
Landslides occur when the stability of a slope changes from a stable to an unstable condition. A change in the stability of a slope can be caused by a number of factors, acting together or alone. Natural causes of landslides include:
Landslides are aggravated by human activities, Human causes include:
Slope material that becomes saturated with water may develop into a debris flow or mud flow. The resulting slurry of rock and mud may pick up trees, houses and cars, thus blocking bridges and tributaries causing flooding along its path.
I took my love, I took it down
I climbed a mountain and I turned around
And I saw my reflection in the snow covered hills
Till the landslide brought me down
Oh, mirror in the sky, what is love?
Can the child within my heart rise above?
Can I sail through the changing ocean tides?
Can I handle the seasons of my life?
Well, I've been afraid of changing
'Cause I've built my life around you
But time makes you bolder
Even children get older and I'm getting older, too
Well, I've been afraid of changing
'Cause I've built my life around you
But time makes you bolder
Even children get older and I'm getting older, too
Yes, I'm getting older, too
Oh, take my love, take it down
Climb a mountain and turn around
And if you see my reflection in the snow covered hills
Well, the landslide will bring it down
And if you see my reflection in the snow covered hills
