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
Trenches were excavated to provide data for relocating buildings damaged by the 2018 earthquake on Mt. Etna. The paleoseismological results along the Fiandaca Fault revealed 3 surface faulting events occurred in: 2018, 1894 and another unknown one in the Early Middle Ages. To verify an increasing trend in seismicity, fault scarps were analysed obtaining movements over different timescales, starting from 115000 years ago, suggesting a very recent growth in flank instability on Etna eastern flank.

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.
