Yesterday evening, Etna opened a vent at the base of the Southeast Crater cone. On the LiveCam you can see a bright spot coming from a short lava flow. According to INGV, the vent opened at 17:00 in the northeast, at an altitude of 2800m. We have observed similar events several times in the last years. Often there was a paroxysm after a few days of lava flow activity. Tremor and seismicity are so far inconspicuous, the lava seems to escape without much pressure. It is quite possible that this is the material that intruded under the crater 2 weeks ago.
