Etna: strombolian eruptions at NSEC

Last night Etna showed its strombolian side and produced further eruptions from the New South East Crater. Glowing tephra was ejected up to 100 m high, which was quite photogenic. At peak times MIROVA registered thermal radiation with a power of 144 MW.

This morning the activity seems to have decreased, MIROVA only registered a thermal anomaly of 36 MW power. In addition, the Thermalcam shows no more thermal radiation around the last active vent. But there seems to be more activity in the central crater. Possibly the small lava flow is still pouring into Bocca Nouva. It originated at the new intracrater cone of Voragine. The tremor is clearly increased and gives an indication that this activity is continuing. The video shows the status-quo on Friday.
