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

Rock fracture under upper crustal conditions is driven not only by applied stresses, but also
by time-dependent, chemically activated subcritical cracking processes. These subcritical …

High-temperature treatment may cause changes in physical and mechanical properties of
rocks. Temperature changing rate (heating, cooling and both of them) plays an important …

The accuracy of elastic analytical solutions and numerical models, widely used in
volcanology to interpret surface ground deformation, depends heavily on the Young's …

Supercritical geothermal systems are appealing sources of sustainable and carbon-free
energy located in volcanic areas. Recent successes in drilling and exploration have opened …

Mechanical characterization of hydrothermally altered rocks from geothermal reservoirs will
lead to an improved understanding of rock mechanics in a geothermal environment. To …

Abstract Acoustic emissions (AE), compressional (P), shear (S) wave velocities, and
volumetric strain of Etna basalt and Aue granite were measured simultaneously during …

To monitor both the permanent (thermal microcracking) and the nonpermanent (thermo‐
elastic) effects of temperature on Westerly Granite, we combine acoustic emission …

Most studies of thermally induced cracking in rocks have focused on the generation of
cracks formed during heating and thermal expansion. Both the nature and the mechanism of …

Time-dependent brittle deformation is a fundamental and pervasive process operating in the
Earth's upper crust. Its characterization is a pre-requisite to understanding and unraveling …
