    A landslide near Cusco, Peru in A NASA model has been developed to look at how potential landslide activity is changing around the world. The term landslide or less frequently, landslip, [1] refers to several forms of mass wasting that include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows.

Landslides at volcanoes share many of the attributes of landslides in nonvolcanic terrain. The similarity of morphology and texture of many volcaniclastic deposits extending beyond the flanks of volcanoes with those of landslide deposits in other mountainous terrain led to the relatively recent recognition that these major mass movements are also common at volcanoes.

On hillsides with soils rich in clay, little rain, and not much vegetation to hold the soil in place, a time of high precipitation will create a mudflow.

Mudflows follow river channels, washing out bridges, trees, and homes that are in their path. Debris flows are accelerated downhill by gravity and tend to follow steep mountain channels that debouche onto alluvial fans or front, or 'head' of a debris-flow surge often contains an abundance of coarse material such as boulders and logs that impart a great deal of ng behind the high-friction flow head is a lower-friction, mostly liquefied flow body.

Abstract. The present paper deals with the flow of bulk solids comprised of discrete particles. Attention will be focused on understanding the interactions that take place between individual particles at the microstructural level as a means to establish the constitutive relationships (expressions for stresses, energy fluxes, energy dissipation, etc.) that govern the flow of Cited by: Overview.

We drop something accidentally or purposely and see its motion. At the beginning it has low speed and until the end it gains speed and before the crash it reaches its maximum speed. Which factors affect the speed of the object while it is in free fall.

Newton's major goal was to explain planetary motion. As mentioned earlier, Johannes Kepler had devised three laws of planetary motion without the use of Newton's law of gravity. They are, it turns out, fully consistent and one can prove all of Kepler's Laws by applying Newton's theory of universal gravitation.

The initial coherent stage is best described by solid mechanics, whereas the flow-like portion is well described with a fluid mechanics solution in the context of an SH model as discussed earlier.
