The lava effusion continues at decreasing, but still considerable rate. When seen yesterday evening, only one channel, 5-10 m wide was still entering the sea at 10 m wide front, while there had been up to 7 branches reaching the shore in the area west of or partially covering the 2007 lava delta. Small explosions were occurring at the sea entry.
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.

from INGV's update this morning:
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.

Different from the overflows during July and yesterday evening, this time, the northern side of the NE crater was affected. First, it seems that a significant collapse occurred, accompanying the opening of a new effusive located at the northern base or flank of the NE crater. How much of the crater itself was affected is difficult to judge at this point.
A collapse event at 05:18 marks the opening of the vent:
