A Significant cause of landslide is related to increased water infiltration which causes saturation of soil. It may be due to ploughing or poor organisation of drainage on a sloping area that has under-gone modification due to deforestation and urbanisation.
Causes of Landslides: There are several factors which lead to the occurrence of landslides. Seismic activity, intensity of rainfall, steep slopes, rigidity of slopes, highly weathered rock layers, soil layers formed under gravity, poor drainage these all are natural factors that cause the landslides.
While landslides are considered naturally occurring disasters, human-induced changes in the environment have recently caused their upsurge. Although the causes of landslides are wide ranging, they have 2 aspects in common; they are driven by forces of gravity and result from failure of soil and rock materials that constitute the hill slope.Several common causes of landslides are: Water: Perhaps the most common trigger of a landslide, water reduces the friction between the bedrock and the overlying sediment, and gravity sends the debris sliding downhill. In sand and clay soils, a small amount of water may increase stability. You've likely seen this when building a sand castle or working with clay. However, the sediment gets.Although gravity acting upon an increased slope is the main reason for a landslide, there are other elements that contribute to its cause. Loud sounds that occur during an earthquake also cause landslides. Erosion caused by rivers, glaciers, or ocean waves create oversteepened slopes. Heavy rains and melting snow weaken rock and soil slopes.
Almost every landslide has multiple causes. Slope movement occurs when forces acting down-slope (mainly due to gravity) exceed the strength of the earth materials that compose the slope. Causes include factors that increase the effects of down-slope forces and factors that contribute to low or reduced strength. Landslides can be initiated in slopes already on the verge of movement by rainfall.Read More
Essay on Landslides in India. Article shared by. A landslide is the rapid sliding of large masses of bed rocks or regoliths. Whenever mountain slopes are steep there is a possibility of large disastrous landslide. Landslides are triggered by earthquakes or sudden rock failures. They can also result when the base of a slope is over steepened by excavation or river erosion. Image Source.Read More
Landslides and slope instability cause problems in many parts of the world. A landslide is primarily a combination of several geological processes that include earth movements like extensive slope failure, rocks falling, and debris flow. These ground movements may take place in a coastal, offshore, or far onshore environment. Gravity, in addition to other factors that affect ground stability.Read More

The cause of a landslide that has to do with the structural combination of rock, soil and vegetation is the morphology. If a hillside has lost vegetation because of a fire for instance, then the addition of water can cause erosion, upping the chances for a landslide. It’s not only rain that can cause erosion but flowing rivers, moving glaciers, and crashing ocean waves. The geology or.Read More
Scientists who have conducted research on the disaster-prone areas have warned that soil-piping is a major cause for the landslides witnessed in these places and the high ranges of Kerala will likely be worst hit if this continues. Also known as 'tunnel erosion', soil piping is the subsurface erosion of soil caused by percolating waters to produce pipe-like conduits below the ground.Read More
