From: Trigger mechanism and propagation dynamics of pyroclastic density currents at basaltic volcanoes
a Skysat scene acquired on 14 February 2022, where the area covered by the PDC deposit (brown layer) is visible. The positions of the 2002–2003 craters, the wooden shelter, and the summit craters (North East Crater: NEC; Voragine: VOR; Bocca Nuova: BN) are also reported. The inset (b) shows the RGB composite (Bands 12, 8, 4) of the Sentinel 2 image acquired on 11 February 2022. c, d Photos showing the PDC deposit seen from a proximal and distal point, respectively; the height of the vehicles in the (c) is about 3 meters (photos by D. Andronico). e Details of the burnt wooden shelter (photo by F. Ciancitto).
