Eruption updates & news from Stromboli:
Stromboli volcano (Eolian Islands, Italy): weak explosive activity at summit vents, increased CO2 emissions

Strombolian acttivity at the summit vents of Stromboli (INGV)
Lava effusion seems to have stopped completely since about a week ago. Small strombolian explosions continue to occur sporadically from vents in the northern and central crater terrace at the summit.
CO2 flux measured on Stromboli (INGV)
The apparent low activity may be the "calm before the storm": a surge in CO2 gas emissions since the beginning of November indicates that fresh magma might be on the rise within the conduit (CO2 being the least soluble magmatic gas and the first to leave the new magma).
One possibility is that the arrival of new magma leads to a strong initial (and very dangerous) explosion. This scenario occurred in 2003 and 2007 during similar stages of activity (after the end of a sustained lava flow).
Stromboli volcano (Eolian Islands, Italy): mild strombolian activity and weak lava effusion continue

Occasional mild strombolian explosions occur from the summit vents. Very weak lava effusion also continues, at least intermittently from the vent at 650 m elevation. (Source: INGV Catania latest report) [more]

The effusive eruption that had started on 7 August seems to be ending: the lava flow emitted from the 650 m vent at the eastern base of the summit crater complex has decreased a lot two days ago and seems to have almost (or completely) stopped by today. ... [more]

No major changes have occurred at the volcano: Lava effusion continues from the 650 m vent and feeds active lava flows on the upper Sciara del Fuoco. From the lava flow fronts, incandescent blocks detach and roll down the slope. ... [more]

There are no signs the effusive eruption is slowing down. A lava flow is being erupted from the vent at 650 m elevation and currently feeds two active branches on the upper Sciara del Fuoco. ... [more]
