Kliuchevskoi (Kamchatka): The eruption of the volcano continues with little changes during the past weeks - there are now two active lava flows on the SE flank, both about 2 km long from the summit crater.

Explosive activity (ash emissions) has so far been minor, with occasional small to moderate ash plumes that have been rising approx. 1-2 km above the summit: for instance, Tokyo VAAC reported a plume at 23,000 ft (7 km) altitude that extended SE yesterday morning:
Karymsky (Kamchatka): The volcano has been very calm recently although "weak activity" continues (KVERT). The aviation color code is currently yellow.
Shiveluch (Kamchatka): The lava dome remains active and continues to grow slowly although activity is currently rather towards the lower end of the volcano's long-term average.
Occasionally, parts of of the dome collapse into small to moderate pyroclastic flows such as occurred yesterday morning, producing associated ash plumes that rise a few kilometers.
Bezymianny (Central Kamchatka Depression): According to KVERT, "a weak gas-steam activity of the volcano continues. Satellite data showed the volcano was quiet." The Aviation Color Code remains at yellow.
Alaid (Northern Kuriles): According to KVERT, weak (eruptive?) activity of the volcano continues. Satellite data showed a thermal anomaly over the volcano.
The latter in fact has become stronger during the past week again.
Kuchinoerabu-jima (Ryukyu Islands): The Japan Meteorological Agency (JMA), the official government body in charge of monitoring volcanoes, lowered the alert level for the island, after no more significant activity has occurred at the volcano since 19 June 2015 (i.e. almost one year).
Current level was lowered from the second highest on the scale (4: "prepare for evacuation") to now 3 ("Do not approach the volcano").

Bagana (Bougainville Island, Papua New Guinea): Darwin VAAC reported several small ash plumes drifting west from the volcano today and during the past days, suggesting that mild eruptive activity continues at the volcano.
Sinabung (Sumatra, Indonesia): The volcano observatory recorded several small pyroclastic flows from the volcano during the last night (at 21:20 pm, 21:27, 22:08, and 00:23 local time).
Most of the eruptions could not be seen directly due to fog, but one of the glowing avalanches was observed to have traveled 1000 m to the south-southeast and 2000 meters to the southeast-east.

Dukono (Halmahera): Near-continuous moderate ash emissions remain visible on satellite imagery on almost every day, indicating that activity inside the volcano's crater remains high (strong degassing, ash venting, intermittent explosions as observed from the rare visitors).
This morning, a gas and ash plume extended approx. 100 km to the west of the volcano.
Santiaguito (Guatemala): Heavy rainfalls in recent days generated strong lahars (mud flows) through the Nima I River bed, remobilizing some of the recently erupted loose volcanic debris.
The turbulent hot flows reached 30 m width and carried blocks up to 50 to 70 cm in diameter, tree trunks and large branches.
Pacaya (Guatemala): The activity at the volcano has started to increase during the past days. Explosion sounds and visible incandescence have become stronger.
According to the latest bulletin of INSIVUMEH, this is also reflected by an increase in seismic amplitude, likely reflecting the rise of new magma. It is possible that the activity at the surface will soon evolve further, producing stronger strombolian explosions, or even lava fountaining, and/or the effusion of a new lava flow (something Pacaya's activity has been typical for).
Turrialba (Costa Rica): A new phase of activity has begun at the volcano. Starting from 20:00 local time yesterday evening, tremor increased, followed by ash emissions since 01:30 this morning.
The activity has been near-continuous and producing a moderately large plume of ash drifting into westerly directions. Light ash fall is expected in downwind areas of the Valle Central.
