Northern vents of Bocca Nuova View of the northern vent area of Bocca Nuova, looking into the crater from its northern rim, on 14 June 1997. View of Bocca Nuova from the western crater rim on 29 July 1997, with the erupting northern vent area at left. An incandescent fountain is rising from a vent in the northern part of the complex cone growing in this area. The main vent seen in activity four days earlier is strongly fuming but not erupting.
Recent lava covers much of the crater floor to the south of the northern eruptive vents.
View into Bocca Nuova at dawn on 5 August 1997, standing on the northern crater rim. Occasional bursts from the southeastern vents that evening, however, were significantly larger than any activity seen in this photo, and dropped bombs onto the southern crater rim and beyond. Zoom on main vent at the northern cone at dawn on 5 August 1998, showing vigorous spattering and fountaining.
