In Indonesia, activity continues on several volcanoes according to a usual pattern in recent days
- The Agung, often covered with fog, presented a small white plume at 100-200 m. above the summit.
Seismicity is characterized by a deep volcanic earthquake, 7 superficial volcanic earthquakes and 5 emission earthquakes.
- The Sinabung did not have eruptions yesterday, and the summit was overcome by a low emission of steam rising between 100 and 600 meters above the main crater
These two volcanoes remain on alert level IV
- The Dukono, in alert level II, is not observable for two days because of the fog, but the eruptive activity continues there.
