Relatively intense activity at Stromboli volcano Eolian Islands in Italy

The activity at the “Lighthouse of the Mediterranean” has been much more intense recently than during most of the year.
Explosions mainly from the eastern vent (towards Stromboli village) have been observed at intervals of approx. 10 minutes, ejecting dense jets of incandescent lava to up to estimated 150 m height.
Continuous glow can be seen from adjacent vents in the central crater area as well, suggesting a relatively high lava column inside the conduit.

Intense activity continues, possible lava flows outside the caldera at Erta Ale volcano in Ethiopia

Activity remains elevated at the volcano in the Danakil. The latest available information show simultaneous effusive activity from both the north and the south crater – the latter, which contained the famous lava lake has been overflowing and building a new lava shield that started to partially fill the summit caldera.
It seems that lava flows have started to overflow even outside the caldera through the low part of the rim on the NE side (judging from satellite data).
