Sezione di Catania - Osservatorio Etneo (INGV) reported that eruptive activity continued at Stromboli during 4-10 November. Webcam images showed Strombolian activity at four vents in Area N within the upper part of the Sciara del Fuoco and from at least three vents in Area C-S (South-Central Crater) on the crater terrace. The vents in Area N continued to produce low-to-medium intensity explosions at a rate of 4-9 events per hour, ejecting lapilli and bombs less than 150 m above the vents. Spattering continued and was sometimes intense, especially on 6 and 9 November. Explosions at the vents in Area C-S ejected tephra more than 250 m above the vent at a rate of 1-3 events per hour.

Intense spattering at Area N began at 1916 on 6 November and intensified within a few minutes. Lava overflowed the crater and descended the Sciara del Fuoco, producing blocks that rolled down to the coastline. The activity lasted for a few hours. Spattering at 0938 on 7 November again intensified within a few minutes and caused the descent of lava along the Sciara del Fuoco. The episode lasted about an hour. During 8-10 November intense spattering caused the flow of incandescent material on the upper part of the Sciara del Fuoco.

Geological Summary. Spectacular incandescent nighttime explosions at Stromboli have long attracted visitors to the "Lighthouse of the Mediterranean" in the NE Aeolian Islands. This volcano has lent its name to the frequent mild explosive activity that has characterized its eruptions throughout much of historical time. The small island is the emergent summit of a volcano that grew in two main eruptive cycles, the last of which formed the western portion of the island. The Neostromboli eruptive period took place between about 13,000 and 5,000 years ago. The active summit vents are located at the head of the Sciara del Fuoco, a prominent scarp that formed about 5,000 years ago due to a series of slope failures which extends to below sea level. The modern volcano has been constructed within this scarp, which funnels pyroclastic ejecta and lava flows to the NW. Essentially continuous mild Strombolian explosions, sometimes accompanied by lava flows, have been recorded for more than a millennium.
