When observed last evening (18 Oct) during the ongoing tour to Italy's volcanoes, we observed small to medium-sized strombolian activity mainly from the western and from the eastern vents:
The western vent continues to produce ash-rich explosions, with abundant glowing material reaching 80-150 m height and falling back onto the outer crater slopes, generating glowing avalanches that often reach the sea. Ash plumes typically rose 3-400 m and drifted over the eastern and southern part of the island, where an almost constant light ash fall could be noted. Intervals of explosions were about 4-8 minutes.
The eastern cluster of vents erupted less frequently, about every 20-30 minutes, generating small glowing fountains that reached 50-100 m height, and almost no ash.
Continuous glow suggests that other vents are emitting incandescent gas and/or displaying small lava spattering. Access to the summit area remains strictly closed.
