One of the biggest challenges in volcanic hazard assessment is to understand how and why
eruptive style changes within the same eruptive period or even from one eruption to the next …

Fused filament fabrication (FFF), an additive manufacturing technique, unlocks alternative
possibilities for the production of complex geometries. In this process, the layer-by-layer …

Extension fractures in volcanic systems exist on all scales, from microscopic fractures to
large fissures. They play a fundamental role in the movement of fluids and distribution of …

The ingestion of volcanic ash by jet engines is widely recognized as a potentially fatal
hazard for aircraft operation. The high temperatures (1,200–2,000° C) typical of jet engines …

Pore connectivity is a measure of the fraction of pore space (vesicles, voids or cracks) in a
material that is interconnected on the system length scale. Pore connectivity is …

Sintered materials are used as permeable filters and flow controllers, for which a validated
and general model of porosity and permeability is required. Here, we prepare samples built …

In sedimentary basins and volcanic edifices, granular materials undergo densification that
results in a decrease of porosity and permeability. Understanding the link between porosity …

Silicic volcanic eruptions range in style from gently effusive to highly explosive, and may
switch style unpredictably during a single eruption. Direct observations of subaerial rhyolitic …

The ease at which exsolving volatiles can migrate though magma and outgas influences the
explosivity of a volcanic eruption. Volcanic rocks often contain discrete discontinuities …

The thermal properties of volcanic rocks are crucial to accurately model heat transfer in
volcanoes and in geothermal systems located within volcanic deposits. Here we provide …
