PROCESS landslides

The process of landslides can be explained as follows.

     The water seeped into the ground will add weight to the ground.
     If water penetrates the soil impermeable pellet acts as a field, the soil becomes slippery.
     Furthermore, soil weathering that are in it will move to follow the slope and off the slopes.

CAUSAL FACTORS landslides

Factors contributing to the movement of the slope also depends on the condition of the rock and soil slope preparation, structural geology, rainfall, vegetation cover and use on the slopes. However, the outline can be distinguished as Natural Factors and Human Factors.

A. Natural factors

     Geological conditions, weathered rocks, the slope of the insertion layer, a layer of clay rock, fault structures and ketear, earthquakes, stragtigrafi, and volcanoes.
     Climate, such as rainfall.
     Topography circumstances, such as steep slopes.
     Tata water circumstances, such as a clogged drainage conditions and the accumulation of water masses.
     Land cover that reduces shear resistance, eg critical ground.

B. Human Factors human tantrum that is not friendly to nature include:

     Cutting climbing on rock mining on steep slopes.
     Hoarding of land on the slopes.
     Failure of retaining wall structures.
     Deforestation.
     Raising fish pond on the slopes.
     Farming systems that do not pay attention to irrigation is safe.
     Development areas that were not matched by public awareness thus self-defeating.
     The slopes of the drainage system is not good.
