Batu Tara (Sunda Islands, Indonesia): Activity at the volcano is relatively intense at the moment. Several ash plumes rising to 5-7,000 ft (1.5-2.1 km) altitude, originating from stronger-than-normal strombolian explosions, were seen on satellite imagery during the past days.
Etna (Sicily, Italy): A violent phase of explosive / effusive activity began over night. Strombolian activity at the New SE crater and volcanic tremor started to increase last evening. This increase continued throughout the night and this morning,- great luck for those on our current tour to Stromboli – Vulcano and Etna.
At the moment, tremor is stagnating, and it is not clear whether the current eruptive phase will culminate in a true paroxysm (lava fountaining).
Near-continuous explosions from the several vents at the summit of the NSEC occur in rapid succession and eject glowing spatter to heights of 100-200 m during in what could be described as pulsating lava fountains. A vent at the eastern part of the summit occasionally ejects dark jets of ash. Brown ash plumes rise from time to time from the northeastern rim of the crater, presumably from collapse events.
Unfortunately, heavy cloud cover, and thunderstorms around noon/early afternoon that deposited approx. 10 cm of fresh hail prevented detailed observations during most of the afternoon.
Sangeang Api (Indonesia): Small ash emissions continue at the volcano. VAAC Darwin last reported a volcanic ash plume rising to approx. 7,000 ft (2.1 km) and extending 30 nautical miles to the NW on Saturday.
Kavachi (Solomon Islands): Some intermittent eruptive activity seems to be occurring at the volcano. On 10 June, another spot of discolored water had been visible above the shallow submarine volcano.
Pavlof (Alaska Peninsula, USA): Based on seismic data, eruptive activity continues at the volcano according to the Alaska Volcano Observatory. However, it has significantly dropped (if not stopped) over the past week. No hot spot is currently visible on satellite imagery.
No ash emissions or lava fountains could be detected recently. A weekly alimented lava flow could still be seen on satellite data from 9 June.
Shishaldin (United States, Aleutian Islands): Low-level eruptive activity continues at Shishaldin, although nothing was observed in cloudy satellite images over the past 24 hours. Web camera views of the volcano were obscured by clouds. (AVO)
Semisopochnoi (United States, Aleutian Islands): The earthquake swarm at the volcano that started on June 9 and escalated on June 12 continues. No eruptive activity is currently indicated and nothing was observed in cloudy satellite images over the past day. (AVO)
