Just few days after the official alert level had been decreased, a massive explosion occurred last night at 02:53 local time, generating an ash plume that rose up to 15 km altitude (50,000ft).
The height of the plume was estimated by VAAC Tokio using satellite imagery. It quickly drifted and dissipated in southerly directions. Even if the plume was (which is likely) a bit smaller than the estimate, it illustrates that the volcano is unpredictable and capable of producing strong eruptions.
Local news channels have reported ashfall on south-eastern Aceh.
According to seismic data, the event lasted more than 7 minutes and produced a very strong signal (120 mm amplitude).
