Reykjanes (Reykjanes peninsula (SW Iceland)): (24 Feb) Given the impending eruption within the next few days, the Icelandic Met Office published the most likely scenarios of the next eruption to occur.
Scenarios (taken from the IMO)

…24 Feb:
Recent model calculations reflect that approx. 5 mil. m3 of magma has been accumulated in the magma reservoir under the Svartsengi region as of 22 February.
Therefore, the possibility of an imminent eruption in the area of the Sundhnúkur crater row is highly likely. Volcanologists estimate about 8-13 mil. m3 volume of magma to be erupted. Judging from the apparent pattern, the next eruption could start early next week if magma will keep the current discharge rate.
The IMO added: „If an eruption occurs, scientists estimate that magma will most likely propagate from the reservoir beneath Svartsengi towards Sundhnúkur crater row, resulting in lava fountaining and lava flows in the area between Stóra-Skógfell and Hagafell. The primary signal of ascending magma is a sudden increase in seismic activity with many localized, small magnitude earthquakes. Considering the previous volcanic eruptions in the area, an eruption could start with very little warning (less than 30 minutes), depending on where magma reaches the surface on the Sundhnúkur crater row. It should be noted that there is a degree of uncertainty in this interpretation, and it cannot be assumed that the behaviour will be identical to the past eruptions here. Also, as the magma plumbing system evolves, we cannot rule out the possibility that the volume of magma required to trigger a new diking event and/or eruption may become reduced.“

Manam (Papua New Guinea): (24 Feb) The volcano remains active.
The latest satellite image from 23 February revealed a strong glow in the southern summit crater. This could reflect a new batch of magma shifting inside the volcano’s conduit accompanied by a degassing. The second northern summit crater continues to be active constantly, meaning the detected glow and near-constant emissions of gas and water vapor suggest continued rise of fresh magma. Although both craters are active, most observed eruptions have originated from the southern crater.
Lewotobi (Flores): (24 Feb) The volcano’s activity has only dominated by the effusive eruption over the past week.
The lava on the north-northeast flank remains active, feeding the flow front that advances slowly through the edifice’s foothills on the northeast. The lava development is well documented in the attached false colour visualization within a two-week (2 Feb-17 Feb) time range.
