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 …

The microstructure and mineralogy of volcanic rocks is varied and complex, and their
mechanical behaviour is similarly varied and complex. This review summarises recent …

An evidently precursory acoustic emission (AE) time series, characterized by a time‐
reversed Omori law, is registered prior to the unconfined catastrophic rupture of brittle …

During the reawaking of a volcano, magmas migrating through the shallow crust have to
pass through hydrothermal fluids and rocks. The resulting magma–hydrothermal interactions …

When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

A primary goal of volcanology is forecasting hazardous eruptive activity. Despite much
progress over the last century, however, volcanoes still erupt with no detected precursors …

Freeze-thaw weathering effectively deteriorates the physical and mechanical properties of
rocks and seriously threatens the stability of engineering projects in cold regions. This study …

Early warning signals of critical transitions in rock before its sudden failure are key for
forecasting geological disasters in rock engineering. Here we examined the critical slowing …

Catastrophic failure in brittle, porous materials initiates when smaller-scale fractures localise
along an emergent fault zone in a transition from stable crack growth to dynamic rupture …

The early prediction of violent coal-bearing strata failure using effective monitoring is crucial
to avoid losses due to catastrophic failures and geological disasters to ensure safe and …
