Landslides is the movement of slope-forming material in the form of rocks, rombakan materials, soil, or a mixture of these materials, moving down or out of the slope.
Landslides occur when the force driving on slopes greater than the drag force. Style retaining force is generally influenced by the density of rocks and soil. While driving style is influenced by the amount of slope angle, water, load and soil density of rock.
The process of landslides is water that seeped into the soil will increase the weight of the soil. If the water until the soil through which water-resistant slide acts as the field, then the ground becomes slippery and the decay above ground will move to follow the slope and exit slopes. Landslides common symptoms include the appearance of cracks in the slope that is parallel to the cliff, usually occurs after a rain, the appearance of new springs suddenly, brittle rock and gravel from falling Factors that cause landslides include heavy rain early in the season , the slope or the steep cliffs, the land is less dense and thick, which is less strong rock, the kind of rice cultivation system, farming, and a puddle of water on a steep slope, vibration, shrinkage of the lake water level or, abrasion / erosion., the material pile on the cliffs, the former long avalanches, deforestation, and waste disposal areas. 
Therefore we need to learn the cause, the occurrence, disaster conditions and disaster management procedures in a disaster area that was devastated by landslides and landslide-prone, so we dapet meminimalis prevent or greater impact again. This is the video for you enjoy it:
