Details are yet unclear, but from the image we received from Stromboli, it was another massive explosion from the summit vents, producing an ash plume that rose probably a few km, ejected bombs to the upper slopes of the volcano and caused a pyroclastic flow that traveled down the Sciara into the sea.
It is not clear whether any appreciable precursors could be detected. Activity had been very high during the past weeks and the summit area was already closed, which hopefully prevented any injuries or worse. From webcam images, nothing very unusual could be detected in the minutes before, just a relatively strong (but not unusual) eruption from a vent in the northeastern crater at 11:55 local time.
In the eastern shore area of the island (Scari), centimeter-sized lapilli are falling.
This time, the eastern and northeastern flanks of the mountain above the village of Stromboli have been hit more by bombs than during the 3 July paroxysm (which had mainly affected the southern and western slopes above Ginostra). Bush fires are visible in areas down to approx. 250-300 m.
We embed a video taken from a boat escaping the pyroclastic flow(s) that descended the Sciara and traveled over the sea. It shows that there were actually two flows next to each other, eventually merging towards the shore. Most likely, at least some if not all of the material forming the pyroclastic flows originated from collapsed portions of the crater terrace where lots of new materials had been deposited during the intense activity of the past weeks.
Impressive pictures of the ash plume rising approx. 4 km above the volcano can be found everywhere on social media:
