Note steep flank of the NE Crater cone toward the Voragine, formed by collapse during the two powerful Voragine eruptions on 22 July 1998 and 4 September 1999. Wide angle view of the Voragine from N on 23 August 2000. The rim of the central pit is visible in the lower middle ground, and a white gas plume is being emitted from the small vent on its S rim. Behind the crest visible behind and to the left of the dense white gas plume lies the Bocca Nuova. Zoom on the small S vent of the Voragine on 23 August 2000.
Central vent is visible in the foreground.
S vent of the Voragine on 27 September 2000. Gas emission is less vigorous than one month earlier, but mild Strombolian activity has begun a few days earlier at the E vent of the Bocca Nuova, which lies behind the crest in the background. A look into the central pit of the Voragine from its NW rim on 27 September 2000. On that day gas emission from this vent was more vigorous than during the 23 August visit. Smaller S vent is at extreme right of the photo.
