For a few days, the activity of the crater of the Voragine of Etna had strongly decreased. This morning May 24, 2020, activity showed a slight increase for a few hours, and one of the explosions produced this magnificent ring of vapor, seen from the region of Monte Grosso, on the south side of the volcano.
