Roundup of Global Volcanic Activity

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.

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.

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).
