Roundup of Global Volcanic Activity

Zhupanovsky (Kamchatka, Russia): The eruption at the volcano that was initially reported by a pilot who observed a 6 km ash plume continues with smaller ash emissions. While the initial report left some doubts about the eruption, confirmation was soon after provided by the presence of a SO2 plume, ash deposits visible on satellite imagery and photos taken on location. The attached photo shows ongoing ash emissions the morning of 7 June following the main explosion. Two secondary flank vents producing steam plumes and dark streaks on the lower left flank of the volcano representing mud flows that were generated by lava-snow interaction are visible.

Semisopochnoi (United States, Aleutian Islands): Another remote volcano in Alaska is showing signs of unrest or possible activity. The Alaska Volcano Observatory (AVO) sent out the following alert: "A swarm of earthquakes at Semisopochnoi volcano that started at 10:00 AKDT (18:00 UTC) on June 9 escalated yesterday, June 12, at approximately 12:00 AKDT (20:00 UTC). The continuation of this anomalous seismic activity through the night prompts AVO to raise the Aviation Colour Code to YELLOW and the Volcano Alert Level to ADVISORY. No eruptive activity is currently indicated.

Etna (Sicily, Italy): No changes in activity have occurred. Sporadic small strombolian explosions continue from the summit crater of the New SE crater. Tremor is low.
