Etna volcano (Italy): SE crater eruption and lava flows March 2017
Impressions from the second eruptive phase of Etna volcano in 2017, when new lava flows were erupted from a fissure vent at the southern base of the SE crater complex. These lava flows descended into the Valle del Bove at several locations on the rim between 2500-2700 m elevation. On their descend down the steep western headwall, the lava flow fronts suffered partial collapses and interacted explosively with snow, both leading to the generation of small pyroclastic flows that produced tall brown ash plumes.
