PVMBG reported that an eruption at Sinabung was recorded at 0253 on 25 May. An ash plume from the event drifted W and NW according to the Darwin VAAC; fog prevented ground-based visual observations. Ashfall was reported in several areas downwind according to a news article.
At 0629 on 27 May a dense gray ash plume rose 2.5 km above the crater rim and drifted S. The VAAC reported that at 0700 an ash plume was visible in satellite images at an altitude of 6.1 km (20,000 ft) a.s.l., or 3.7 km above the crater rim. Eruptive events were recorded at 2323 on 27 May and 0118 on 28 May, though ash plumes were not visible.
The Alert Level remained at 3 (on a scale of 1-4), with a general exclusion zone of 3 km and extensions to 5 km on the SE sector and 4 km in the NE sector.
