In Etna, Boris Behncke reports the opening a few days ago of a new hole / "puttusiddu" on the southern side of the cone of the saddle of the crater SE, source of the last two eruptive episodes (27.02 to 01.03.2017 and 15 to 20.03.2017)
The third eruption of 2017 continues at the Fuego with moderate to strong explosions.
The plumes of ash are raised up to 5,000 meters asl, with fallout on a sector west-southwest. Long lava flows of 3,000 meters affect the Trinidad, Las Lajas and Honda barrancas. A risk of pyroclastic flows weighs on the barrancas Las Lajas and Ceniza.
