April 28, 2015 - EARTH - The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe, courtesy of Volcano Discovery.
Karymsky (Kamchatka): An explosion occurred this morning that was strong enough to produce an ash plume to approx. 10,000 ft (3 km) altitude (VAAC Tokyo).
Sakurajima (Kyushu, Japan): Strong activity continues from the volcano. This morning (14:24 local time), an explosion at the Showa crater sent a plume to 15,000 ft (4.5 km) altitude that drifted north.
Manam (Papua New Guinea): Eruptive activity is taking place at the volcano. VAAC Darwin reported an ash plume to 8,000 ft from the volcano this morning. A pronounced SO2 plume can be seen on satellite data as well.
Dukono (Halmahera): The volcano continues to produce significant ash emissions - a plume extending 20 nautical miles E was observed Saturday (Darwin VAAC).
Barren Island (Indian Ocean): A pilot reported an ash plume rising to 10,000 ft from the volcano. Likely, eruptive activity which had produced a new lava flow in March is still going on or has resumed.
