The mechanical behaviour and failure modes of volcanic rocks: a review
MJ Heap, MES Violay - Bulletin of Volcanology, 2021 - Springer
The microstructure and mineralogy of volcanic rocks is varied and complex, and their
mechanical behaviour is similarly varied and complex. This review summarises recent …

Hydrothermal alteration of andesitic lava domes can lead to explosive volcanic behaviour
Dome-forming volcanoes are among the most hazardous volcanoes on Earth. Magmatic
outgassing can be hindered if the permeability of a lava dome is reduced, promoting pore …
