Landslide (land slides) is a natural phenomenon of a type of corrosion that causes damage to the area, a high Hill or mountain with a. Very steep due to the lack of balance in the aforementioned area. Cause of ground towards the Earth's gravity and movement of. The area of geological elements from low to high. Landslides frequently occur in the case of makboriwen mountain torrent and mount it to absorb the water until saturated to cause erosion (environnet, Department of environmental quality promotion) Can be divided according to the kind of landslide movement 3 features:1) landslide which moved slowly Creep Creep such as Surficial called.2) landslide that moved quickly, called Flow, such as Surficial Slide or Slide.3) landslide that sudden movement called Rock Fall Fall.Landslides in the country, Thailand Most birth torrent makboriwen, later the mountain River area now. The country, which are factors that promote severity of landslides. Is as follows:1) rain on the mountains.2) slope of mountain3.) the integrity of the forest.Geological characteristics of 4) mountains.The series of landslides occurred when torrent water into the ground quickly. While the land mass of water adhesion between approaches, the ground will be reduced. The water level beneath the surface up to make the flow resistance of the soil decreased. When the water surface level under the high-flow within the space of ground. Down the slope of the ramp, he When there is a change of slope, it will be the first to pop up and the water has to flow, Earth's. When the soil occurs, the flow will be continuous, and up along the slope of the Hill.
