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.
