Pyroclastic density currents (PDCs) are dangerous multiphase flows originating from
volcanic eruptions. PDCs cause more than a third of volcanic fatalities globally and …

This review article provides an overview of dry granular flows and particle fluid mixtures,
including experimental and numerical modeling at the laboratory scale, large scale …

GEOphysical flow dynamics using pulsed Doppler radAR (GEODAR), a custom radar
system, images avalanches over the entire slope with high spatial and temporal resolution at …

Pyroclastic density currents (PDCs) are hazardous and destructive phenomena that pose a
significant threat to communities living in the proximity of active volcanoes. PDCs are ground …

Avalanche risk management is strongly related to the ability to identify and timely report the
occurrence of snow avalanches. Infrasound has been applied to avalanche research and …

Powder snow avalanches (PSAs) are destructive flows as high as 200 m descending at
frontal speeds of up to 100 ms− 1. Dry snow PSAs typically develop a dilute frontal region …

Automated detection of snow avalanches is crucial to assess the effectiveness of avalanche
control by explosions, and to monitor avalanche activity in a given area in view of avalanche …

Five avalanches were artificially released at the Vallée de la Sionne test site in the west of
Switzerland on 3 February 2015 and recorded by the GEOphysical flow dynamics using …

Rockfalls are ubiquitous products of landscape evolution in steep mountainous terrains.
Among other effects, they pose a significant concern to the management of transportation …

Continuous and spatially distributed data of snow mass (water equivalent of snow cover,
SWE) from automatic ground-based measurements are increasingly required for climate …
