Short summary
Short summary
Under a NATO project, we installed a monitoring system at the Khoko landslide facing the Enguri artificial reservoir (Greater Caucasus). During 2016–2019, we compare slope deformation with meteorological factors and variations in the water level of the reservoir. Our results indicate that the landslide displacements appear to be controlled by variations in hydraulic load and partially by rainfall.

Short summary
In the framework of the NATO Science for Peace and Security Program, we have increased the knowledge on the geohazards affecting the Enguri hydroelectrical plant (Caucasus, Georgia). 2 km from the dam, active deformation (2–5 cm yr−1) affects a slope facing the water reservoir. Our field, seismological and numerical analyses show that the worst scenario is represented by seismic shaking with a local peak ground acceleration capable of generating an unstable rock volume of up to 48 ± 12 × 106 m3.

Short summary
Palaeoseismological techniques applied with artificial trenches at three deep-seated gravity slope deformations (DSGSDs) in the Alps document extensional deformation and reverse slips. The data indicate that reverse slip might occur both at the toe and in the central-upper portions of DSGSDs. The reverse slip is interpreted as due either to locking of the frontal blocks of a DSGSD or to the relative decrease in the rate of downward movement in the frontal blocks with respect to the rear blocks.

Short summary
Short summary
Grain size is a key factor for deformation. Quartz is one of the main constituents of the crust, but little is known about grain growth that can change grain size. We therefore experimentally determined grain growth laws for quartz. We discuss the importance of the grain size exponent, water fugacity exponent, and activation energy. Our results indicate that the contribution of grain growth to deformation may become important in lower-crustal conditions.

Short summary
The Northeast Rift of Mt Etna is affected by ground deformation linked to gravity sliding of the volcano flank and dike injection. Drone surveys show that the rift is affected by NE-striking extensional fractures and normal faults. Given an age of 1614 CE for the offset lavas, we obtained an extension rate of 1.9 cm yr−1 for the last 406 years. The stress field is characterised by a NW–SE σHmin. Drone surveys allow us to quickly collect data with a resolution of 2–3 cm.
