GEOLOGY

Detailed explanation-1: -Landslides are caused by disturbances in the natural stability of a slope. Factors that trigger landslide movement include heavy rainfall, erosion, poor construction practices in mountains, deforestation, earthquake shaking, and volcanic eruptions. Extreme heat is not a cause for landslides.

Detailed explanation-2: -Higher soil clay percentage generally increases landslide susceptibility, whereas higher bulk density and soil organic matter content negatively affect susceptibility.

Detailed explanation-3: -Landslides are large masses of wet or dry rock and soil that fall, slide, or flow very rapidly under the force of gravity. Landslides on volcanoes can occur without any associated volcanic activity.

Detailed explanation-4: -Prepare for landslides by following proper land-use procedures – avoid building near steep slopes, close to mountain edges, near drainage ways or along natural erosion valleys. Become familiar with the land around you. Get a ground assessment of your property if possible. More items
