Etna (Sicily, Italy): Activity from the New SE crater continues essentially unchanged. Weak strombolian activity occurs at the summit vent, sometimes associated with more or less pronounced ash emissions.
When observed last evening, ejections at the NSEC rarely exceeded 50-100 m above the rim and only occasionally, bombs landed on the outer flank. The lava flow, only about 500-600 m long last night and half way down to the bottom of the Valle del Bove headwall, increased over night. It developed a second branch and its most advanced fronts have now reached again the base of the Valle del Bove.
Tremor fluctuates with an overall slowly rising trend. This seems to correspond rather to an increase in effusive(lava flow) than explosive activity.

Shiveluch (Kamchatka): (8 Feb) A phase of intense activity has been taking place at the volcano over the past few days. On 6 Feb afternoon (or early morning 7 Feb in Kamchatka), a large eruption occurred. VAAC Tokyo spotted an ash plume drifting at approx. 27,000 ft (9 km) altitude more than 300 km northwest. The ash plume reached the Sea of Okhotsk and ash fall occurred in the village Sedanka at more than 200 km distance from the volcano.
Unfortunately, webcam images do not allow to determine whether this eruption had been caused by an explosion liberating accumulated pressure, or whether a major collapse of the actively growing viscous lava dome had taken place, producing pyroclastic flows and related co-ignimbrite ash plumes. It is possible if not likely that it was the result of a combination of both.

Kilauea (Hawai'i): (8 Feb) Per HVO, Kilauea's summit lava lake rose by 20m/66ft in the past week, just another 15m/49ft until it's visible from the Jaggar Overlook!
