Sangeang Api (Indonesia): (4 Jun) Eruptive activity continues in the form of low-level ash emissions. VAAC Daarwin reported a volcanic ash plume at estimated 10,000 ft (3 km) altitude extending more than 100 km to the west.

Dukono (Halmahera): (4 Jun) Ash plumes from strong strombolian activity continue to show up as alerts from VAAC Darwin. A plume extending 50 nautical miles to the north was seen last evening. Its height was at estimated 7,000 ft (2.1 km) altitude.

Pavlof (Alaska Peninsula, USA): (4 Jun) After a phase of intense eruptive activity yesterday, the volcano continues to erupt lava fountains and flows, along with associated ash plumes, but has decreased its activity.
Starting around 23:00 local time yesterday evening, the effusion rate increased rapidly, lava fountaining at the summit reached 200 m height and the lava flows on the northern flank became more alimented. As a result of violent interaction between lava and ice/snow, pyroclastic flows formed and descended on the flanks. An associated ash plume rose to approx. 24,000 ft (7 km) altitude and drifted more than 70 km to the east.

Ubinas (Peru): (4 Jun) A relatively strong explosion occurred yesterday morning at the volcano, followed by ongoing ash emissions. Overall, the activity at the volcano has been showing again an increasing trend.
The ash plume was approx. 3 km high and rose to 10 km altitude, then drifted east:
