Based on PVMBG ground-based observations, the Darwin VAAC reported that during 25-27 June ash plumes from Sinabung rose to an altitude of 3.7 km (12,000 ft) a.s.l. and drifted E.
From the comments on social networks, the Sinabung issued 400,000 cubic meters per day pasty lava. A very high rate. Despite this, most of the mass fell apart in the frequent avalanches rather than flows. A geologist at the observatory, said the explosion and pyroclastic flows have removed about 1.4 million cubic meters of the old dome, changing the morphology and redrawing the slope. Now it seems to produce more explosions.
