Karymsky (Kamchatka): An ash plume from an explosion produced an ash plume that rose to 14,000 ft (4.2 km) altitude and drifted north this morning. The volcano continues to produce intermittent strombolian- to vulcanian-type explosive eruptions.

Chirinkotan (Northern Kuriles): Ash emissions were recorded on satellite imagery on 26 July, producing a plume that rose to 15,000 ft (4.5 km) altitude and drifted NW. During yesterday and today, the plume dissipated and no new emissions were detected (VAAC Tokyo).
Kirishima (Kyushu): Elevated seismic activity has been recorded since early July, the Japan Meterological Agency (JMA) reported. Yesterday, a phase of volcanic tremor occurred that lasted 3 minutes and a slight ground deformation was detected.
Whether this is caused by an intrusion of fresh magma which in turn could lead to a new eruption is unclear. For the time being, the volcano's alert level remains at 2 (out of 5) where it has been since Oct 2013. While the recorded signs of unrest are weak, sudden phreatic explosions could occur any time and pose a significant risk if visiting the crater area.
Akan (Hokkaido): A swarm of shallow volcanic earthquakes under the Ponmachineshiri crater of Mt Meakan volcano has been occurring since yesterday. This event triggered the Japanese Meteorological Agency (JMA) to raise the volcanic alert status to 2 (eruption alert, on a scale of 1-5) today.
The swarm follows a gradual increase in seismicity under the volcano noted since April this year. JMA thinks the most likely outcome is a very small (phreatic) eruption in the near future and recommends not to approach the crater within 500 m.
Raung (East Java): The eruption, now over 4 weeks old, continues with no significant changes. Strong lava effusion inside the summit caldera is accompanied by near-constant ash emissions rising 1-2 km and drifting up to 100-200 km in mostly westerly directions.
PS: If you are interested in visiting (climbing) the volcano around 11-15 August, please contact us.
Sinabung (Sumatra, Indonesia): A series of pyroclastic flows yesterday noon (see previous post) and this morning destroyed a part of the eastern lava lobe.

Dukono (Halmahera): Strong ash emissions continue at the volcano. VAAC Darwin reported an ash plume extending 25 km north of the volcano yesterday.
Popocatépetl (Central Mexico): The activity at the volcano has remained more or less unchanged over the past months. During the past days, explosive activity has been a bit higher than average, but alert level remains unchanged at Yelled phase 2.
Intermittent explosions occur from the summit crater, where lava domes slowly grow until a series of stronger explosions destroy it and a new one grows.
Sabancaya (Peru): Light ash emissions have been occurring at the volcano.

Sinabung (Sumatra, Indonesia): (27 Jul) Activity has remained essentially unchanged. Effusion of viscous lava continues at slow pace to feed the lava dome with two active lobes on the SE and E upper flanks. At 12:22 local time today, a small part of the eastern lobe collapsed into a medium-sized pyroclastic flow that traveled approx. 2.5 km towards the outskirts of the (already evacuated and destroyed) villages of Bekerah and Simacem. ...
