Fig. 1 - S2 (26.12.2017) - 4,3,2 natural colour; 11,8,2 with gaussian equalization & NDVI - Volcano Kadavar before its eruption.
Fig. 2 - S2 (15.01.2018) - Still smoking, the Kadovar has traded most of its vegetation for ash, in particular on its southern flank.
Fig. 3 - S1 IW (02.01.2018) - vv,vh,ndi(vh,vv) - The shape of the Kadovar shows its steep southern slope probably collapsed in the past.
Fig. 4 - S1 IW (26.01.2018) - The island expanded east & the southern flank of the volcano shows subtle evolution.
