A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows.
Common names for landslide types include slump, rockslide, debris slide, lateral spreading, debris avalanche, earth flow, and soil creep ( Colorado Natural Hazards Mitigation Plan, 2013). Landslides move by falling, sliding, and flowing along surfaces marked by differences in soil or rock characteristics.

Slope failure can occur due to various natural and human-induced factors. Some of the common causes of slope failure are: 1. Geology and Soil Properties: The type and properties of soil and rock underlying the slope can contribute to instability. For example, slopes with weak or weathered rock, clay soils, or soils with a high water content are mor...
There are several types of landslides, which are classified based on the type of material involved and the way they move. Some of the common types of landslides are: 1. Rockfall: This occurs when rocksor boulders detach from a steep slope and fall to the ground. 2. Rockslide: This occurs when a large block of rock slides downhill along a plane of w...
There are several techniques used for slope stability analysis, including: 1. Limit equilibrium analysis: This method assumes that the slope fails along a failure plane, and the factor of safety is the ratio of the resisting forces to the driving forces along that plane. Different methods can be used for this type of analysis, such as the Bishop’s ...
Landslide Effects. By Educational Resources. This report illustrates, by means of computer animation, how four different types of landslides (slide, slump, flow, and rockfall) occur and what type of damage may result.
Landslide Hazards Program. FAQs. What is a landslide and what causes one? A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity.
44 The Landslide Handbook—A Guide to Understanding Landslides Part A. Evaluating Landslide Hazards There are many different means of assessing landslide hazard for an area; it is always advisable to consult with an expert for the most accurate assessment, although this is not always possible. Two types of landslide hazard evaluation, direct

Jan 25, 2022 · 51 Citations. 25 Altmetric. Metrics. Abstract. Landslides are one of the most important geohazards. In 2004–2016, more than 55,000 people lost their lives to landslides and this does not include deaths caused by seismically triggered landslides. Overall losses were estimated to be at USD 20 billion annually.
