We are beginning to witness more aggressive activity from the world’s eruptive volcanic systems. Chile’s Calbuco, Peru’s Ubinas volcano, Indonesia’s Mt. Sinabung volcano, Mexico’s Colima volcano, and Costa Rica’s Turrialba volcano are not the only volcanoes ejecting high altitude ash plumes in more powerful eruptions these days – the list of volcanoes across the globe now experiencing similar simultaneous activity is growing. Volcanic activity as documented for April 27, 2015:

Karymsky (Kamchatka): (27 Apr) 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): (27 Apr) 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): (27 Apr) 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): (27 Apr) The volcano continues to produce significant ash emissions – a plume extending 20 nautical miles E was observed Saturday (Darwin VAAC).

Barren Island (Indian Ocean): (27 Apr) 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. Extinction Protocol
