Avalanching occurs on slopes underlain by loose granular solids, for example, the slip faces of dunes and deltas and mountain screes, in response to a particle deposition-rate gradient which steepens these slopes to states of instability.
Excessive slope gradients (34°) and pore-water stress (saturation) in glacial till soils are shown to be primary factors in debris avalanche and flow occurrence (slope failure, landslide activity) in recently logged areas. Applicability of soil-mechanics techniques to evaluating factors affecting debris avalanching are discussed.
Avalanches, landslides and debris flows are devastatingly powerful natural phenomena that are far too little understood. These granular matters are mixtures of solid particles and of an interstitial fluid and are easily modelled on the microscopic level by the laws of mechanics.

A debris flow is a moving mass of loose mud, sand, soil, rock, water and air that travels down a slope under the influence of gravity.
Sep 30, 2020 rock avalanches can trigger destructive associated hazards following the to the mechanism of rapid undrained loading of saturated path sediments. The special term rockslide-debris avalanche was previously proposed.
An avalanching effect can also be present, in which the moving mass entrains additional material along its path. Flows [ edit ] slope material that becomes saturated with water may produce a debris flow or mud flow.
His research interests are in geophysical mechanics with applications in the dynamics of glaciers and ice sheets, the mechanics of granular materials, avalanching flows of snow, debris and mud, physical limnology and the foundations of continuum mechanics and thermodynamics.
Debris flows and debris avalanches are among the most dangerous and destructive natural hazards that affect humans. They claim hundreds of lives and millions of dollars in property loss every year. The past two decades have produced much new scientific and engineering understanding of these occurrences and have led to new methods for mitigating.
Based on the comparison between the tancitaro debris avalanche and similar events we propose that mechanical fluidization was the mechanism responsible.
