Volcanos

Roundup of Global Volcanic Activity

Batu Tara (Sunda Islands, Indonesia): During our recent expedition to Batu Tara, we witnessed a spectacular increase in activity during the night 3-4 Nov, culminating in a small pyroclastic flow triggered by a collapsing lava fountain and increased effusive activity from the dome.

Stromboli (Eolian Islands, Italy): Activity has remained low - there is no lava effusion. At the vents in the summit craters, there are occasional small explosions and strong degassing. Tremor is low, and CO2 emissions have decreased a bit over the past weeks. Access to the area above 400 m remains closed.

Fogo (Cape Verde): Volcanic activity continues, but the advance of the lava flows has slowed down to approx. 5 meters per hour and it seems that the effusion rate has diminished. The abundant presence of gases and ash in the area of the Cha das Caldeiras caldera prompts authorities to maintain a total access restriction.
