A Landslide is a descent mass of earth and rock down a mountain slope. Landslides occur in every state. The Appalachian Mountains, the Rocky Mountains and the Pacific Coastal Ranges some parts of Alaska and Hawaii have extreme landslide problems. Any area composed of very weak or fractured materials setting on a steep slope can experience landslides. Landslides usually occur without warning. Landslides may occur when water or melted snow sink through the earth on top of a slope. They also may occur when water seeps through cracks and spaces of sandstone and the layer softens. If the support is weakened, the mass of earth and rock slide down along the layer. Some landslides move slowly over years and cause little destruction. Earthquakes and volcanoes can also cause severe, fast-moving landsides. Landslides affect structures in nature. Landslides can pull down buildings. They can also affect plant-life and the environment through which a slide occurs.
Landslide Effects on Buildings.
Landslides affect buildings. As pressures on the ground increase, so does the likelihood of buildings being ruined. Landslides can occur where terrain has been altered by man or geologically, including roadways.
