Stromboli (Eolian Islands, Italy): The activity at the volcano has strongly increased since about 2 weeks ago. Our group tour visited Stromboli during 8-11 June and observed at least 14 active glowing vents. It appears that the magma level has once again risen to very near the surface of the crater terrace.
About half of them were showing constant or, some, intermittent weak to strong spattering: in particular, the twin vents of the central crater, two vents in the western crater, the NW hornito, as well as, intermittently, the hornito at the northwestern rim of the NE crater.
Typical strombolian explosions, some quite strong with ejection heights to 200-300 m, occurred at intervals of 5-10 minutes mainly from the westernmost twin vents, the NW hornito, the large NE vent, and occasionally also from the central crater. The NW hornito often produced a 3-5 meters tall pale purple flame-like gas jet that usually preceded candle-like eruptions accompanied by very loud jet-engine noises.
