Eruption updates & news from Stromboli:
During the recent tour "From Stromboli to Etna" we observed mild to moderate explosions from Stromboli volcano. The most active vent appears to be in the former central crater, with powerful explosions throwing glowing material up to 200m elevation above the crater and often outside on the N and NE flanks. Other vents in the eastern and western part of the crater erupt occasionally with loud bangs and loud hissing noises produced by strong gas jets.
As our colleague Andrea Ercolani reports from Stromboli, access to the summit area of Stromboli has been reopened for guided tours under certain restrictions. In brief, small groups accompanied with authorized guides can now reach the ridge east of the crater terrace between 750 and around 850 m elevation where a few shelters are located, but the maximum stay is now limited to 30 minutes. Access to the Pizzo summit itself is limited to the time necessary for passing along the trail.
The lava flow from Stromboli volcano stopped today.
Whether this is the end of the effusive eruption that had started 5 weeks ago and heralds the beginning of a new cycle of summit activity is still unclear.
The lava continues to flow on Stromboli. Three branches of lava flows originate at the 420 m vent on the Sciara del Fuoco, two of which still reach the sea.
Today, 21 March, tremor has decreased and thermal camera observations show that at least one of the two branches were no longer alimentated and cooling. ...more
On 15 March at 21.37 local time, a powerful explosion occurred from the summit craters of Stromboli, similar but much weaker than the event on 5 April 2003. Incandescent bombs were thrown onto the flanks of the volcano and created small bushfires. Ash fell on the inhabitated centers of the island, but nobody was killed or injured during the eruption.
The monitoring network registered a slightly increased flux of lava from the 400 m vent immediately prior to the explosion. As a security measure, access to the volcano has been reduced frm 400 m to 290 m elevation.
The lava flow from the 400 m vent at the eastern sector of the Sciara del Fuoco is still active.
Already this morning, the new effusive vent at about 500 m on the Sciara del Fuoco was almost inactive and little remained of the lava flow that started yesterday.
The other lava flow from the 400 m vent continues to be active although the flux of lava seems to be diminuishing. Its front has overlapped the impressive lava delta and continues its groth.
8 March: Pause of the eruption
On 8 March, the lava flow from the 400 m vent below the 2003 lava plateau suddenly ceased almost completely. In the evening, the two branches of the flow and the lava delta at the sea were cooling, only a few red spots were visible from fractures on the surface, and a few glowing blocks and small amounts of sea water steam were still visible at the former entry points. At the vent itself, only a very weakly alimented flow extending perhaps 10-20 m was visible.
