Volcanos

Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): According to the local mountain guides from Magmatrek, activity has increased significantly during the past 3 days, especially at the NW vent. A group of VolcanoDiscovery has arrived on the island and will report in more detail in the following days.

Etna (Sicily, Italy): After about 10 days of near complete quiet, a faint red glow was observed early on 22 Oct at the New SE crater. The origin of the glow seems to have been increased degassing from the summit vent and the at the fumaroles in the saddle between the old and New SE cone.

Karymsky (Kamchatka): An explosion yesterday produced an ash plume rising to 7,000 ft (2.1 km) and drifting SE, VAAC Tokyo reported.

Ibu (Halmahera, Indonesia): Hot spots at the summit have become larger and more frequently observed on recent MODIS satellite data. This indicates that activity has become more intense at the volcano with its active lava dome.

Dukono (Halmahera): The semi-persistent explosive activity of strombolian to vulcanian type has been at elevated levels recently. The volcano produced ash plumes rising to 9,000 ft (2.7 km) altitude yesterday as well as this morning. Our friend Aris reported from a recent visit to the volcano that bombs during this activity were ejected to up to 1.5 km distance from the active crater.

Veniaminof (Alaska Peninsula, USA): No new eruptive activity has been observed recently and MODIS satellite data no longer show hot spots. Seismicity remains above background levels, and AVO maintains alert level yellow.
