Weak ash emissions from Bocca Nuova crater
Update Tue 03 Nov 18:47On November 1st a quite energetic seismo-volcanic event occurred most probably from the Bocca Nuova crater. Since that time there has been a change in the seismic tremor.
During last weekend cloud cover prevented direct observations but today it was possible to observe very weak ash emissions most probably due to the activity inside the Voragine crater.

The emissions originate probably from older material, but according to volcanologists, magma is not far from the surface.
Update Sat 16 May 17:46The eruption has almost ended.
Tremor has descended back to low levels and lava effusion has almost completely ceased and stopped ca. 5 km from eruptive fissure .
The most advanced flow front is slightly below 1700 m elevation just above Rocca Musarra.
Explosive activity and ash emissions seem to have ceased.

Eruption continues- Ash emissions from Bocca Nuova crater
Update Fri 15 May 17:51The eruption continues, although its intensity has decreased compared to yesterday.
Moderate strombolian explosions occur at the summit vent of the New SE crater and lava effusion from the fissure vents at its base continues to feed the lava flow, which since yesterday evening has split into 2 branches in the northern Valle del Bove one descending to the south of Monte Simone and another towards the center of the valley.
At 11:50 (local time ) a moderate explosion occurred at Bocca Nuova crater followed by intermittent ash emissions.

New paroxysm with lava flow into Valle del Bove
Update Thu 14 May 23:36
After the onset of mild strombolian activity on 12 May, activity first decreased during the night 12-13 May and then started to rise again gradually. Early in the morning (between 06:11-06:23 local time), an effusive fissure opened on the eastern flank of the cone, from where a lava flow emerged. Accompanied by violent collapse events, triggering small pyroclastic flows, the fissure enlarged during the morning and lava effusion increased. At the same time, explosive activity at the summit vent continued intermittently.
During the night 13-14 May, the activity - both effusive and explosive - significantly gained strength and tremor continued to rise. By the morning of 14 May, a second effusive vent opened below the first one at the base of the cone, and the lava flow had a length of approx. 1.5 km and had passed Monte Simone in the northern part of Valle del Bove.
During the day until the evening, activity has continued to increase slowly. Strombolian explosions have been merging into low, pulsating fountains and the lava flow has extended more than 4 km by now.

Increasing strombolian activity at New SE crater
Update Tue 12 May 19:55Strombolian activity began again today at the New SE crater. Accompanied by rising tremor, this activity is increasing at the moment.
The current pattern is very similar to many past episodes which often culminated in violent explosive (lava fountaining) and effusive (lava flow) paroxysms and could very well build up to a new one, maybe similar to the previous one during 1-2 Feb this year.

Large lava flow to the SW side
Update Sun 01 Feb 23:43More details start to emerge about the new eruptive phase. Strombolian activity from the SE crater accompanies important lava effusion, feeding an impressive lava flow.
The lava flow has been taking a path to the SW, passing the 2002 cones on their western side and descending already to approx. 2000 m or less altitude, a few km west of the provincial road to La Sapienza.

Strombolian eruptions and lava flow
Update Sun 01 Feb 19:32The new eruptive phase continues. Dense cloud cover has prevented detailed observations, but from occasional clearings and other observations, it seems that the intense strombolian eruptions are going on from a vent between the old and New SE crater, feeding a lava flow, at least 2.5 km long onto the southwestern slope.
Tremor remains high.
