Study Notes
A landslide is a mass movement of material, such as rock, earth, or debris, down a slope. They can happen suddenly or more slowly over long periods of time. Landslides are classified by their type of movement, which can be falls, topples, slides, or flows. They are caused by various external factors, including heavy rainfall leading to ground saturation, erosion of the base of a slope, and changes to the material's strength through weathering. Additionally, human activities like mining, traffic vibrations, and urbanization can also contribute to landslides.
Landslides can have significant impacts, causing fatalities, property damage, and economic losses. In the absence of fatalities, they can still have socio-economic impacts by severing access to remote communities and affecting services, employment, health, and educational opportunities.
Factors that increase the chance of a landslide include the addition of water to the material on a slope, erosion processes, slope angle, rock type, grain shape, jointing and orientation of bedding planes, weathering processes, and vegetation loss. Flooding, volcanoes, and earthquake activity nearby can also contribute to landslide occurrences.
To prepare for a landslide, it is essential to understand the landslide hazard in your area and take appropriate measures. This may include avoiding building on slopes, maintaining vegetation, and being aware of potential hazards during heavy rain or seismic activity.
