Roundup of Global Volcanic Activity

Bardarbunga (Central Iceland): According to Icelandic volcanologist Haraldur Sigurðsson, it is reasonable to predict that the eruption might be ending in March this year. This audacious prediction is based on extrapolating the observed ongoing slow subsidence ("collapse") of the central volcano's caldera floor, located under 800 m of ice, and assuming that it is a direct indicator of the magma erupted at the Holuhraun fissure.

Karymsky (Kamchatka): A small volcanic ash plume was reported this morning extending ESE from the volcano. Karymsky has intermittent strombolian to vulcanian explosions.

Zhupanovsky (Kamchatka, Russia): Intermittent ash emissions continue from the volcano. This morning Tokyo VAAC reported a small plume at flight level 120 (12,000 ft / 3.6 km altitude) extending SE.

Soputan (North Sulawesi, Indonesia): A viscous lava flow lobe is active on the western flank of the summit cone. Spectacular incandescent rockfalls accompany this effusive activity. According to volcano chaser John Seach on twitter, an explosion occurred earlier today, producing a 20,000 ft ash plume and pyroclastic flows. Although this information has not been confirmed by other sources, the eruption, similar to Sinabung's still ongoing one, is entering a potentially very dangerous phase. A safety radius of 6.5 km around the volcano's summit is in place.

Dukono (Halmahera): A moderately strong ash emission, possibly due to increased explosive activity, was reported this morning, reaching 9,000 ft / 2.7 km altitude. (Darwin VAAC)

Cerro Negro de Mayasquer (Colombia): Seismic activity remains high with an average of almost 1200 small quakes detected on a daily basis under the Chiles volcano. However, it has been decreasing overall compared to last year and no events were large enough to be felt recently.

Sangay (Ecuador): A hot spot was detected in satellite data (Washington VAAC), suggesting that some mild activity continues in the summit crater of this remote volcano, one of South America's most active.
