: (16 Sep
) A jewel on the internet - one of (if not THE) most comprehensive and informative websites about Italy's volcanoes (and beyond), Dr. Boris Behncke's Italy's Volcanoes
is back on the internet, in its original version with no retouching.
Even though it is no longer updated, it remains a valuable resource of information about Etna and other Italian volcanoes, with exciting first-hand eye-witness accounts of most of Etna's eruptions during the late 1990's and early years of the new millennium.

Bagana (Bougainville Island, Papua New Guinea)
: An eruption was reported this morning, producing an ash plume rising to 8,000 ft (2.4 km) altitude and drifting 30 nautical miles to the NW (VAAC Darwin).
Batu Tara (Sunda Islands, Indonesia)
: Strong strombolian to vulcanian activity continues. Another ash plume could be spotted on satellite imagery this morning. The estimated elevation was 7,000 ft (2.1 km).
Sinabung (Sumatra, Indonesia)
: The volcano has been calm today and not produced new explosions except some weak ash venting this morning, and continues to show strong degassing. Evacuations of people living in close vicinity continue because the volcano could erupt more violently any time.
A 3 km exclusion zone around the volcano has been put in place. Local press reports suggest that about 6,000 people have been relocated to temporary shelters. Dust masks are being distributed to the population.
Degassing from Sinabung this evening:
: Lava lakes continue to be active in Benbow and Marum craters. A large SO2 plume can be seen on today's NOAA satellite data.
Veniaminof (Alaska Peninsula, USA)
: The eruption seems to be ending. AVO reports that "seismic tremor continues though at decreased levels compared to prior weeks. No unusual activity was observed in webcam images. These data indicate that the effusion of lava from the active vent may be ongoing though diminished."
Santa María / Santiaguito (Guatemala)
: Activity (both explosive and effusive) has been weak recently.
: Strombolian activity has been gradually increasing during the past days. Frequent explosions, at intervals of about 5 minutes, eject glowing material to 50-100 m above the Mackenney crater, and ash plumes drift up to 3 km to the W and SW. The activity is visible from the capital Guatemala city. INSIVUMEH thinks that the appearance of a new lava flow is likely to occur soon.
: Explosive activity has increased a bit recently. INSIVUMEH reports explosions with incandescent tephra reaching 75-100 m above the crater and ash plumes rising up to almost 1 km during the past days. Frequent incandescent avalanches occur from the ejected bombs on the upper slope of the volcano. Light gray ash fall occurred at the observatory (located to the south).
: An explosion was heard last evening (but could not be observed due to cloud cover). Activity, both internal (seismic) and external, remain generally at moderate to high levels, but has been lower today.
A hot spot continues to be visible at the summit.

Batu Tara (Sunda Islands, Indonesia)
: Activity remains strong with frequent explosions of strombolian to vulcanian type. An eruption this morning produced an ash plume detected on satellite images. VAAC Darwin estimated the elevation at 7,000 ft (2.1 km). ... Lees alle
: Lava effusion continues. Since the night 10-11 Sep, the lava has changed path and now feeds a second lava flow a bit to the north from the previous one, making it better visible from the KVERT webcam located north of the volcano. ... Lees alle
Sakurajima (Kyushu, Japan)
: Activity remains elevated. The volcano produces near-constant ash venting and relatively many (3+ per day) vulcanian-type explosions. Ash plumes have been rising up to 14,000 ft (4.2 km) during the past 2 days. ... Lees alle
: The volcano continues to slowly extrude a new lobe of viscous lava from the dome. This process is accompanied by occasional explosions and ash emissions such as one this morning that produced a plume rising to 19,000 ft (5.8 km) altitude. ... Lees alle
: The effusion of a lava flow on the SW flank and strombolian activity at the summit vent continue. Avalanches are being formed from detaching lava blocks from the flow on the steep flow. KVERT reports moderate seismic activity with strong tremor, that obscure the signal from nearby Bezymianny volcano. A large thermal anomaly can be seen on satellite data. ... Lees alle
