Frequent ice avalanche events are being reported across the globe in recent years. On 7 February 2021, a flash flood triggered by rock-ice with an unusually long runout distance, caused significant damage of life and property Tapovan region Indian Himalaya. Using multi-temporal satellite datasets, digital terrain models (DTMs) simulations, here we report pre-event during-event flow characterist...

We report results from a statistical analysis of avalanches of cohesive powders in a slowly rotated drum. Interparticle adhesion, which diminishes the effect of inertia and whose magnitude strongly fluctuates in a local scale, makes avalanches in slightly cohesive powders eligible for displaying self-organized criticality. However, the results show that avalanche sizes, time interval between av...

Neuronal avalanches are a ubiquitous form of activity characterized by spontaneous bursts whose size distribution follows a power-law. Recent theoretical models have replicated power-law avalanches by assuming the presence of functionally feedforward connections (FFCs) in the underlying dynamics of the system. Accordingly, avalanches are generated by a feedforward chain of activation that persi...

Particle fracture, the formation of small particles as result breakage large ones, and aggregation, combination have important implications in industry (e.g. food processing, pharmaceutical production) geophysics (e.g., snow avalanches rock debris flows). Also, presence different size that from fracture aggregation can induce segregation, resulting migration to regions flow. Here, we formulate ...

In this work we study the complexity of the three-dimensional sandpile avalanches triggered by the addition of two critical con…gurations. We prove that the algorithmic problem consisting in predicting the evolution of three dimensional critical avalanches is P -complete and 6 p n-strict hard for P . On the other hand we prove that three-dimensional avalanches are superlinear long on average. I...

The Savage-Hutter (SH) avalanche model is a depth-averaged dynamical model of a fluid-like continuum implementing the following simplifying assumptions: (i) density preserving, (ii) shallowness of the avalanche piles and small topographic curvatures, (iii) Coulomb-type sliding with bed friction angle delta and (iv) Mohr-Coulomb behaviour in the interior with internal angle of friction phi> or =...

Abstract. On 6 February 2023, two major earthquakes occurred in the East Anatolian Fault Zone (EAFZ) of Türkiye. The EAFZ forms east border Plate. magnitude 7.7 and 7.5 Kahramanmaraş – Türkiye Earthquakes that struck southern resulted common destruction 11 provinces region. Total main fault segments ruptured during earthquake sequence on approximately 400 km surface rupture occurred. life losse...

Using numerical simulations we examine colloids with a long-range Coulomb interaction confined in a two-dimensional trough potential undergoing dynamical compression. As the depth of the confining well is increased, the colloids move via elastic distortions interspersed with intermittent bursts or avalanches of plastic motion. In these avalanches, the colloids rearrange to minimize their colloi...
