Ibu volcano (Halmahera, Indonesia), Nov 2014: eruptions

During the volcano tour to Dukono and Ibu volcanoes in November 2014, we climbed and camped at Ibu during 12-13 Nov 2014. The volcano's activity, typical for the recent years, at moderate levels, consisted in intermittent strombolian explosions and ash emissions, accompanying very weak lava extrusion.

Small jets of brown and black ash, along with many small bombs are ejected during an eruption from multiple vents at the eastern base of the cone. The dark (relatively cool) finger-shaped ash jets to the right along with the white steam plumes suggest phreatomagmatic activity (i.e. interaction of water with magma). (Photo: Tom Pfeiffer)
