Yesterday evening at 7:06 PM, an explosive eruption occurred, which was stronger than the everyday eruptions at Stromboli. This is indicated by a report from INGV. The entire crater terrace was covered with tephra. However, according to current knowledge, there were no impacts of larger blocks or bombs on Pizzo or along the Cima, where tourists were previously allowed. In connection with the explosion, two lava overflows also occurred from the northern crater area. The lava fronts quickly reached the upper part of the Sciara del Fuoco. Similar lava overflows had already been observed in the past few days. At that time, the activity was accompanied by lava spattering. I already pointed out last week that lava flows on Stromboli usually form in phases. During such phases, there is also an increased danger of stronger explosions and paroxysms, which can even generate pyroclastic flows extending to the sea.
