Nov 9, 2014 · 2. Definition A landslide, also known as a landslip, is a geological phenomenon that includes a wide range of ground movements, such as rock falls, deep failure of slopes and shallow debris flows. Landslides can occur in offshore, coastal and onshore environments.
Dec 16, 2012 · This document discusses landslides, including their causes, types, effects, indicators, prevention, and safety measures. It defines landslides as the downward movement of soil, rock, and vegetation under gravity. Key points include that landslides occur when resisting forces are less than driving forces, and can be triggered by heavy rainfall ...
Jul 11, 2016 · This document discusses geological hazards caused by landslides. It defines landslides as the downward sliding of land mass along steep slopes due to gravity. Heavy rains, earthquakes, floods, terrain cutting and droughts are among the main causes.
1 Landslides. 6 INTRODUCTION A landslide is a downward or outward movement of soil, rock or vegetation, under the influence of gravity. Resisting forces prevent the mass from sliding down the slope The resisting forces can significantly reduced in case of rain or earthquake vibrations.
Land Classification of Earth Movements All movement of land masses are referred as landslides, but differ in many respects, therefore all types of landslides are categorized as Earth Movements.
Aug 17, 2023 · This lecture covers the causes and prevention of landslides, as well as the different types of landslides such as earthflows, rock slides, and mudflows. It also discusses the importance of slope reduction and constructing retaining walls to prevent landslides. Slideshow 9113546 by edgarj.
May 19, 2012 · Learning Objectives • Understand basic slope processes and the causes of slope failure • Understand the role of driving and resisting forces on slopes and how these are related toslope stability • Understand how slope angle and topography, vegetation, water, and time affect both slope processes and the incidence of landslides ...
The primary cause of landslide is the influence of gravity on weakened material that make up a sloping area of land. Other factors that may cause landslide can be categorized in the following areas: geological factors, morphological factors, physical factors and factors associated with human activities.
Jul 17, 2024 · Landslide, the movement downslope of a mass of rock, debris, earth, or soil. Landslides occur when gravitational and other types of shear stresses within a slope exceed the shear strength (resistance to shearing) of the materials that form the slope.
Apr 26, 2024 · A landslide is the movement of rock, earth, or debris down a sloped section of land. Landslides are caused by rain, earthquakes, volcanoes, or other factors that make the slope unstable. Geologists, scientists who study the physical formations of Earth, sometimes describe landslides as one type of mass wasting.
