They move out or down along a planar surface with little tilting, and can travel great distances. Pushing the rock is easier if the surface slopes downhill or is slippery. For existing communities built on or near landslides, mitigation measures retaining trees and native vegetation on slopes, or keeping downspouts and driveways from draining onto slopes, for instance can reduce the potential of landslides reactivating. Any change to the Earth's surface that increases the slope (for example, river incision or the removal of material at the base of a slope by humans) or that reduces the friction of a slope (such as the addition of water) can increase the likelihood of a landslide. Debris avalanches are unchannelized debris flows that move very rapidly. Some landslides may provide clues that they are about to happen; others may happen suddenly without any warning signs. PO Box 40220 The initiation of slides, like flows or rockfalls, is sensitive to steep slopes, the additional weight of water or other loads, and friction along their base. Posting comments is now limited to subscribers only. Back-tilting may occur near the scarp of the landslide and there is often a toe of displaced material. Water is not only heavy, increasing the driving force of a slope, but it pushes soil grains apart, insinuating its way between the tiniest particles. Deep-seated landslides can cover large areas and devastate infrastructure and housing developments. Sudden changes in creek water levels, sometimes with increased sediment, especially during or right after large or protracted storm events. Understanding how and why these landslides move help geologists develop mitigation techniques and determine future hazards for roads, houses, infrastructure, and human life. Always drain surface runoff away from slopes, fix plumbing leaks that could saturate soil, and plant and protect native ground cover and trees. The Chicago Tribune called Lightfoot .

A .gov website belongs to an official government organization in the United States. Landslides are complex, often moving in numerous different ways, from small shallow slumps and rock topples to deep-seated landslides. Remember: If you build walls to divert debris flow and the flow lands on a neighbors property, you may be liable for damages. Erosion caused by loss of ground cover can lead to flash flooding.

These surveys were performed at irregular intervals between July 1, 2014 and July 7, 2015. What Are Landslides And How Do They Occur? The landslides high mobility was likely due to several contributing factors, including the soils initial porosity and water content from rainfall in the months prior.
