Sangeang Api (Indonesia): VSI decreased the alert level from 3 to 2 ("Waspada", on a scale of 4), as seismic activity has decreased recently.
Eruption plume from Popocatepétl yesterday
Soputan (North Sulawesi, Indonesia): VSI decreased the alert level back to level 2. The volcano is currently quiet and only degassing.
Merapi (Central Java): A small ash eruption was reported yesterday at around 09:15 local time. Residents near the volcano heard an explosion sound and some fins ash fell on nearby villages.
Veniaminof (Alaska Peninsula, USA): The volcano began erupting on Thursday morning, June 13, following several days of increasing seismicity, AVO reported. The official Color Code/Alert Level was raised to ORANGE/WATCH.
At least a small lava flow was erupted. A pilot observed an ash plume up to about 12,000 ft above sea level and a lava flow issuing from the intracaldera cinder cone. Residents in Perryville and Port Moller also reported observing the ash emissions at about 11:30 pm AKDT yesterday. Observers located west of the volcano reported that no ash was issuing from the intracaldera cinder cone this morning; however ash emission could resume abruptly at any time.

Pavlov (Alaska Peninsula, USA): Weak activity continues. Persistent elevated surface temperatures consistent with lava effusion were observed in satellite images, and minor ash plumes below 20,000 were generated through most of the week and mostly drifted to the southeast. There were no reports of ash fall on local communities. On Thursday, pilots reported observing no ash emissions. (AVO)
Popocatépetl (Central Mexico): Activity has picked up during the past 2 days, as the preceding earthquake swarm had suggested. CENAPRED reports emissions at a rate of 2 per hour. The more vigorous explosions have produced ash plumes of up to 3 km height. The largest was an explosion yesterday just before 17:30 (local time).
A large SO2 plume is emitted from the volcano and visible on NOAA satellite data.
