The study of volcanology is traditionally covered by experimental volcanology, field volcanology, geochemistry, rheology, geophysics and analytical modelling. Recent developments have consisted of applying rock mechanics and rock engineering techniques to volcanology, including field, laboratory and numerical modelling techniques. This abstract highlights how laboratory experiments focussing on strength, stiffness and permeability have demonstrated the complexity of volcanic rocks. This abstract also presents how these laboratory results have been used to develop conceptual models of volcanic processes, which can help with decision making regarding volcano monitoring and hazard assessment.
