During 21-28 January, seismic data, web camera views, and satellite images all indicated that low-level ash emissions at Veniaminof continued. Seismicity was similar to levels observed during the previous week, consisting of low-amplitude volcanic tremor with occasional larger bursts. During periods of clear weather, satellite imagery showed anomalous heat at the summit cone, consistent with hot blocks and ash being ejected from the active vent.

RVO reported that an eruption at Manam during the evening of 27 January was more severe than other eruptions that have occurred during the current eruptive period. Debris from the eruption was voluminous and widespread on the island. RVO's monitoring base at Warisi village was completely destroyed by a possible pyroclastic flow, preventing RVO from providing information on the current level of activity.
