Volcanoes are unstable structures that deform laterally and frequently experience mass
wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes …

Abstract The 1980 eruption of Mount St. Helens was instrumental in advancing
understanding of how volcanoes work. Lateral edifice collapses and the generation of …

Abstract La Fossa Caldera at Vulcano (Italy) has been showing signs of unrest since
September 2021. To investigate this phenomenon, we conducted an analysis of geodetic …

The genesis of particles and their transport mechanisms are the two fundamental factors
driving the accumulation of sediments associated with volcanism or derived from volcanic …

Volcano slope stability analysis is a critical component of volcanic hazard assessments and
monitoring. However, traditional methods for assessing rock strength require physical …

Volcano observatory best practice recommends using probabilistic methods to forecast
eruptions to account for the complex natural processes leading up to an eruption and …

Volcanic edifices are composed of an assortment of materials with varying mechanical
behaviours. The range in mechanical behaviours of these rock materials presents a critical …

Diagnostic absorption features in hyperspectral data can be used to identify a specific
mineral or mineral associations. However, it is unknown how accurate hyperspectral …

Lava domes form by the effusive eruption of high-viscosity lava and are inherently unstable
and prone to collapse, representing a significant volcanic hazard. Many processes …

Hydrothermal alteration is generally associated with the weakening of volcanic rocks. Here
we evaluate the possible role of hydrothermal alteration in lava dome collapses at Mt …
