Stromboli volcano (Eolian Islands, Italy): major lava flow

This post will be updated on this special page.
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:
