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 …

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 …

Microcracking due to thermal stresses affects the mechanical and flow properties of rocks,
which is significant for thermally dynamic environments such as volcanoes and geothermal …

Thermal treatment may cause changes in microstructure of rock, which has a significant
influence on rock behaviors. Heating time (ie, duration) is an important aspect in the thermal …

The geometry of voids in porous rock falls between two end-members: very low aspect ratio
(the ratio of the minor to the major axis) microcracks and perfectly spherical pores with an …

Recently, projects have been proposed to engineer deep geothermal reservoirs in the
ductile crust. To examine their feasibility, we performed high-temperature (up to 1000° C) …

The knowledge of the structure of volcanoes and of the physical properties of volcanic rocks
is of paramount importance to the understanding of volcanic processes and the …

Large temperature changes may cause degradation in physical and mechanical properties
of rocks. This degradation can be influenced by heating-cooling procedure. In this study, it is …

With a low mechanical strength and high Poisson's ratio, coal can exhibit brittle or ductile
deformation when exposed to lower levels of stress, strain rate, pressure, and temperature …
