BPPTKG reported no notable morphological changes to Merapi's summit lava dome, though the dome just below the SW rim had increased about 2 m in height during 31 December 2021 to 6 January 2022. The estimated dome volumes were over 1.67 million cubic meters for the SW dome and just over 3 million cubic meters for the summit dome. The intensity of the seismic signals remained at high levels.
As many as 69 lava avalanches traveled a maximum of 2 km SW down the Bebeng drainage. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 3-5 km away from the summit based on location.

Visual observations of our expedition leader and guide from VolcanoDiscovery Indonesia, Andi Volcanist, confirm that the huge actively growing southwest lava dome poses a high risk of sudden collapse and destabilization of the accumulated material that may turned into dangerous turbulent pyroclastic flows. ...
