Stromboli’s Sciara del Fuoco this morning with the still weakly active lava flow (image: LGS webcam)

The lava flow has decreased significantly in intensity during last night, but according to the volcano observatory still remained weakly active today. Judging from webcam imagery, however, it appears it might more or less have stopped by this evening.

No other significant changes in the activity at the summit craters – spattering and intermittent explosions from several vents – have been reported.

Starting from 17:30 local time, volcanic tremor once again started to rise sharply and from around 18:20, intense strombolian activity started at the New SE crater, producing dense ash plumes that rose a few 100 meters and drifted into easterly directions.

This activity seems to be still increasing and if continues might well lead up to yet another paroxysm, this time less than 24 hours since the previous one!

The effusive-explosive eruption of the volcano continues and remains essentially unchanged at moderate levels.
The lava, keeping the flow active, continues to effuse from the NE crater onto the Sciara del Fuoco and slowly reaching about 400-500 m elevation, i.e. half way down to the sea.

Strombolian-type explosions and spattering continue from several of the summit vents.
Incandescent material from the margins and front of the flow slid down along the Sciara del Fuoco and reached the sea.
According to MODIS Detection System a high thermal anomaly (129-331 MW) was detected in satellite images.
Sulfur dioxide (SO2) emissions reached to a 494 tonnes/day.
