UAVs have become a useful tool for natural hazard monitoring. In volcanic areas, they allow
wider observations of the eruptive behaviour, with no risk for the operator. The SfM
technique enables obtaining orthoimages of lava flows and a DEM in a short time. These
data are also useful to estimate lava flow volumes and the mass output rate characterizing
an eruption. We present the results of ten UAV surveys made during and after the 30 May –
6 June 2019 eruption of Etna volcano, projecting the data in a time context back until 1999.
Orthoimages taken on different days allowed monitoring the morpho-structural evolution of
the fissures, capturing the lava flows propagation and the accumulation of pyroclastic
deposits. From 1999 to 2018, there were nine flank-eruptions and dozens of summiteruptions,
which for graphic simplicity have been grouped by year in the map. The resulting
map represents the most updated of the recent lava flows of Etna
