Continuing lava flows
Update Sat 09 Aug 10:47

Stromboli's lava flows yesterday night
Several lava branches were still weakly active on the upper Sciara, causing many incandescent rockfalls.
It appears that a part of the NE flank of the NE crater has collapsed and that the new effusive vent is located at its northern base, at approx. 700 m elevation. Thus, being lower than the summit vents, it is able to effectively drain the upper part of the volcano's plumbing system, which explains why no explosions were observed at the summit craters.

Lava flows reaching the sea this morning (INGV thermal webcam)
At 05:16 GMT on 7 August, the second abundant lava flow began as an overflow from the northern terrace, quickly covered the entire "plateau" at 600 m altitude, and then descended the Sciara in several branches.
In a short time, the lava flows reached the sea in several fronts. The activity was accompanied by numerous landslides. The left image, taken by the camera SCT at 06:23 GMT on August 7, shows three lava flows entering the sea, while two others, in the foreground, are close to reaching the coastline.
Update Thu 07 Aug 10:59
The lava flow is entering the sea and has covered the 2007 lava flow.

The beginning of the new flow
A collapse event at 05:18 marks the opening of the vent:

15 minutes later, the lava flow front arrives at the edge of the 2002-3 plateau.

Within minutes, the lava then descends the Sciara del Fuoco

A major event has taken place about half an hour ago. It seems - judging from available webcam imagery - that a new vent opened at the NE base of the crater and/or a significant part of the crater terrace might have collapsed and left space for a larger lava flow descending the Sciara.
Videos (time-lapse from INGV's webcam on Sciara del Fuoco, thermal and visible):
Yesterday's new lava flow had started as an overflow from the notch between the two prominent N1 and N2 vents, commonly known as the NE crater. A series of smaller and larger collapse events had occurred during the day, most notably at 14:06, 14:24 and 14:51.
These events likely coincide with the beginning of the lava flow. The flow itself, similar to the ones that had occurred in July, remained active until the early morning, but had significantly decreased by then.
A picture taken from the sea on the evening shows that the flow had not reached the sea:

Rockfalls / lava flow on the Sciara on 6 Aug afternoon (image: Civil Protection)
Between 09:13 and 17:23 that day, deformation in the outer flanks of the NE crater was detected - the area where the landslide and new flow started on 7 Aug.
