Etna (Sicily, Italy): Turi Caggegi succeeded in capturing yesterday's lava fountains, several hundreds of meters high and from several vents spraying in different directions, on video:
Ash emission from Sinabung volcano today
The eruption is already ending with an abrupt drop of volcanic tremor and decreasing lava emission. Judging from the few webcam images with at least some visibility, it appears that the activity was more effusive (lava flows) than explosive (lava fountains) with the main phase being around 23:20 local time.
Shiveluch (Kamchatka): A series of larger dome collapse events took place today, producing large pyroclastic flows and an ash plume that rose to about 30,000 ft (10 km) altitude.

Nishino-shima (Volcano Islands, Japan): The new island continues to erupt and grow, increasing its chances of long-time survival by the day. The active vent on the islet continues to be in strombolian eruption and has by now built a new cone that is higher than the main island itself (which is 38 m).
Lava flows have significantly enlarged the island to the SE where a plateau is being built. During the 10 days, it has more than doubled its surface.

Sinabung (Sumatra, Indonesia): Moderate ash emissions continued today, with estimated plume heights of 12,000 ft (3.6 km) altitude.
Kerinci (Sumatra): According to a local news article, an increase in earthquake activity prompted the local volcano observatory to issue an alert prohibiting mountaineers from climbing to the 3,805 meter tall stratovolcano's peak. VSI maintains the volcano at alert level 2 (out of 4).

Etna (Sicily, Italy): A new paroxysm has started at the New SE crater. Following weak strombolian activity during the past days, this afternoon, started to rise steeply this afternoon. At the time of this update, there are increasingly strong strombolian explosions or pulsating lava fountains at the New SE crater and an ash plume has started to rise. Bad weather inhibits good observations, but occasional views can be obtained especially from the NE side. You can follow the eruption "live" at our interactive webcam viewer. ... [meer...]
