38.789°N, 15.213°E; summit elev. 924 m

All times are local (unless otherwise noted)

INGV reported that during 6-10 August, a new lava overflow occurred from the crater terrace of Stromboli in the central part of the Sciara del Fuoco. This new lava flow began on 6 August accompanied by large landslides of hot material that reached tens of meters onto the ocean surface. On 7-9 August, a second lava overflow occurred from the north of the crater terrace that covered a plateau at 600 m elevation and six arms of the flow reached the sea. Explosions from lava/sea interactions produced jets of steam, ash and blocks the rose tens of meters into the air that continued 10 August.

Geologic Background. Spectacular incandescent nighttime explosions at this volcano have long attracted visitors to the "Lighthouse of the Mediterranean." Stromboli, the NE-most of the Aeolian Islands, 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 horseshoe-shaped scarp formed about 5,000 years ago due to a series of slope failures that extend 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.
