Since the entrance of the lava into the Valle del Bove at the end of the night on 16 March, Etna's activity remained stable on 17 March, with a level of tremor stable.
It is characterized by a strong strombolian activity at the central vent of the Southeast Cone, with fountaining, intersected by significant emissions of ash.

The eruptive fracture at the base of the cone is responsible for an effusion, which is reflected on the different photos by three entries of lava in the Valle del Bove.
Incandescence remains visible at the level of La Voragine.
