The Voragine crater on Mount Etna was seen spattering lava on June 26, as the renewed Strombolian activity continued there after three years of quiet.Footage by Giuseppe Tonzuso shows the crater spurting lava.Strombolian activity is a relatively low-level volcanic eruption, during which a modest amount of energy is released, according to the National Institute of Geophysics and Volcanology.“A few weeks ago a small activity began inside the Voragine crater, an activity that has become more spectacular in recent days,” Tonzuso told Storyful.
