Why does the summit of Etna change so quickly? Insights from aerial photos, thermal images, footage and structural field observations.
Neri M., De Maio M.
Etna is among the world's most active volcanoes and its uppermost region is continuously changing. This involves that updated DEM are continuously required to run lava flow models for hazard estimation. Here we present new morphostructural data of the Etna's summit. High-resolution photos, thermal images, footage from a helicopter and LiDAR ground measures were processed to obtain a orthophotography of the target zone. These data and structural field observations allow defining the deformations of Etna's edifice in the last decades. Our data show how flank instability may control the distribution of volcanism, including the shift of the summit vents.
