According to the First Information Report (FIR) on the Wayanad landslides prepared by the Geological Survey of India, the velocity of the debris flow was 57 m/s (190 ft/s). The debris flow originated as a debris slide at an elevation of 1,544 metres (5,066 ft), then followed the river's path, carrying tons of rock and soil mixed with water ...
A debris flow in Ladakh, triggered by storms in 2010. It has poor sorting and levees. Steep source catchment is visible in background. Debris-flow deposits are readily recognizable in the field. They make up significant percentages of many alluvial fans and debris cones along steep mountain fronts.
Debris flow channel scoured out by the passage of a debris flow. A flow is a spatially continuous movement in which surfaces of shear are short-lived, closely spaced, and usually not preserved. The distribution of velocities in the displacing mass resembles that in a viscous liquid.
Landslides, also known as landslips, skyfalls or rockslides, [3] [4] [5] are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. [6] Landslides occur in a variety of environments, characterized by either steep or gentle slope ...
It is a common middle stage in the transformation of a cohesive debris flow from a landslide or rockslide. Debris avalanches may be restricted to grain flows or granular flows, in which flow mechanics are governed by particle interactions involving friction and collision. Debris flows, in contrast, owe much of their behaviour to excess pore ...
A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses en masse and not in individual blocks. Note that a rockslide is similar to an avalanche because they are both slides of debris that can bury a piece of land.
Categorised as "rain induced debris flow" [5] [27] the landslide was characterised by rapid water flow at a steep gradient, flowing at high velocity from the rocky outcrops through the shola forest collecting loose material along its course to the tea plantation and worker’s living quarters below.
The International Consortium on Landslides is a non-governmental organization created in 2002 to promote landslide research, education, and risk evaluation and reduction. It is located in Kyoto, Japan. The organization has consultative status with UNESCO. [1] [2] The ICL's journal is Landslides. It holds regular symposiums, including the World ...
