Sometimes from unstable soil, or sometimes from areas that are saturated by heavy rains that destabilizes the ground, soil and rocks. Also ground tremors and earthquakes cause landslides. The vibration of heavy traffic on a highway may generate enough force to cause a landslide.

What Causes Landslides
2016-11-07 10:28:55 · answer #2 · answered by arshad 4 · 0⤊ 0⤋
An unstable substructure,and especially if it is weighted down by moisture. The grade of the slope will have a factor in the amount and rate of landslide. A good growth of trees and vegetation can have an impact on slowing a landslide. The landslide can originate due to the moisture, an earth tremor or the soil conditions, or a combination of all three. Do we get an "A"

Answers:
Earthquakes shake the surface of the earth and cause landslides.
Wind and Water erosion of the soils and sands cause landslides.
Mudslides are caused by heavy rains exceeding the moisture retention level of certain soils which then become a kind of pliable mush and shift downward due to their weight.
In certain special cases loud noises can also be enough to trigger a landslide which was about to happen for other reasons. Gunshots, thunder crashes, explosions, or even jet plane sound might be sufficient to trigger these very sensitive situations.

Instability in the soil or rock. As you may recall from physics, things that are up high have potential energy that they'd like to release.
Piles of soil or rock like to be in a cone-shaped pile whose slope is a function of the effective friction of the soil or rock. Water, being a great lubricant, changes the friction and allows the pile to readjust its slope.
Earthquakes and volcanic eruptions can cause fractures or fissures in hillsides to develop, which can then be precipitated into landslides as well.

Rain + Dirt = Mud
If the mud is on a hill it will slide down
because thats what gravity does
Thus, land slide

loose earth... usually due to lack of plantlife (roots) to hold the ground together... and usually after a dryspell and the ground has become very brittle,,,. then after rain soaks the ground and makes it all heavy,,, it just collapses under its own weight
