Volcanoes Today, 27 Apr 2015: Karymsky volcano, Barren Island, Dukono, Sakurajima, Calbuco, Manam
Monday Apr 27, 2015 10:00 AM |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).
Calbuco (Southern Chile and Argentina): Activity has been lower yesterday, but weak ash emissions continued at least intermittently.
Sernageomin reported decreasing levels of seismic activity yesterday, dominated by 283 volcanic-tectonic quakes mostly at 8 km depth, as well as weak volcanic tremor. It is unclear whether the eruptive phase is ending or heading towards a new phase of magmatic activity, with the possible scenario of new larger exposive and/or effusive (lava flows, lava dome emplacement) activity.
A main hazard at the moment is the occurrence of lahars, mudflows that are generated when rainwater mobilizes the abundant fresh ash deposits.
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.
