On 4 November, bubbling, a strong sulfur smell, and micro-telluric tremor were observed in the sea near Panarea Island in the Aeolian Archipelago. The submarine hydrothermal activity killed hundreds of fish. According to Stromboli On-Line, the temperature of the water in the area was not very high (~25°C). They stated that an intensification of degassing and consequent bubbling occurred in the area surrounding the small islet of Lisca Bianca, about 2 km E of Panarea.

Geological Summary. The mostly submerged Panarea volcanic complex lies about midway between Stromboli and Lipari in the eastern part of the Aeolian Islands. Panarea, the smallest island in the Aeolian Archipelago, lies on the western side of a shallow platform whose shelf margin is at about 130 m depth. A series of small islands breach the surface to form the Central Reefs, the rim of a crater 2 km E of Panarea, whose shallow submerged floor contains Roman ruins. The submerged Secca dei Pesci lava dome lies at the SE end of the platform, and the rhyolitic Basiluzzo lava dome rises 165 m above the surface at the NE end, along a ridge trending towards Stromboli volcano. The complex was constructed in two main stages: an initial effusive activity phase that produced lava domes, and an explosive stage. The youngest subaerial airfall-tephra deposits are dated to about 20,000 years ago; a date of less then 10,000 BP on a lava flow is uncertain. Vigorous hydrothermal activity has continued at fumarolic fields at several locations on the submerged platform; submarine hydrothermal explosions have occurred in historical time.
