How are landslides formed
WebBasins formed by tectonism, volcanism, and landslides Tectonism —or movement of the Earth’s crust—has been responsible for the formation of very large basins. Late in the Miocene Epoch (about 23 to 5.3 million years ago), broad, gentle earth movements resulted in the isolation of a vast inland sea across southern Asia and southeastern Europe. WebDue to less erosion at the front of the glacier a corrie lip is formed. After the glacier has melted a lake forms in the hollow. This is called a corrie lake or tarn.

WebLandslides due to human intervention is one of the causes of landslides in India. One such is deforestation. For example, the Himalayan region has become more vulnerable to landslides due to the indiscriminate cutting of trees. Removal of trees reduces the binding properties of soil and rocks. WebLandslides occur when masses of rock, earth, or debris move down a slope. Debris flows, also known as mudslides, are a common type of fast-moving landslide that tends to flow in channels.

They can also result from the eruption or collapse of island or coastal volcanoes and from giant landslides on marine margins. These landslides, in turn, are often triggered by earthquakes.
