Fig. 1 — Multi-vent structure of the crater terrace of Stromboli, imaged during a UAS overflight on 6 June 2018. Indicated are main degassing areas (N Northern, C Central and S Southern) with numbers indicating separate vents. In response to the distinct eruptive behaviour and degassing characteristics observed, we retain these as separate vent areas rather than adopt the dual characterisation (N and SW + C) previously proposed. Lowercase letters indicate the location of individual intracrater vents where more than one is present. Inset are images of explosions from vents N1 and S1_a, and incandescence and passive degassing within C_b.
