A new paroxysm is occurring at the volcano. Increasing near-continuous strombolian eruptions occur from the summit vent of the New SE crater and a lava flow is issuing from a vent at its eastern base into Valle del Bove. Tremor is still rising.
Lava flow and strombolian activity this evening
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.

The 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. read all
