Collapse Risk
Introduction
A landslide or slide,[1][2] is the movement of a large mass of earth that falls off a slope or slope "Slope (geography)"), rushing towards it.[3].
Landslides can be caused by earthquakes, volcanic eruptions, or instability in surrounding areas.[4] Landslides are often exacerbated by human development, such as urban expansion,[5] and resource exploitation (such as mining and deforestation).[6][7] Soil degradation often results in less soil stabilization by vegetation. In addition, global warming may increase the frequency of natural phenomena and extreme weather conditions that trigger landslides.[8].
Mudslides (mudslides) are a special type of landslide caused by water that penetrates the ground due to strong precipitation (precipitation (meteorology)), modifying it and causing the landslide. This occurs with some regularity in various places such as during rainy periods.[9].
Types of landslides
Landslides
Landslides occur when a large mass of land or unstable area slides with respect to a stable area, across a surface or strip of land of small thickness. The slides begin when the strips reach the maximum tangential stress at all points. Landslides are a type of landslide that is engineering avoidable "Prevention (extreme natural phenomena)"). However, in general the other types of landslides are not avoidable.
mud flow
Landslides consisting of mud flows occur in very rainy areas, affecting very large areas. Clay soils, upon coming into contact with water, behave as if they had reached the liquid limit and move more slowly than landslides. It occurs in small slopes, but in large quantities.[9].
The thicknesses vary according to the stratigraphic configuration of the site of occurrence of the phenomenon, and hence its effects on the area of influence. Although it can be said that engineering is not possible to avoid it, the effects can be mitigated by applying basic bioengineering and environmental engineering criteria.
