On Kadovar, the Rabaul volcano Observatory informs us of a continuous lava flow from the south-east costal vent, and the formation of a connection with an emerging lava island.

Between February 14 and 22, steam plumes are emitted by both the main crater and the costal vent, interspersed on February 16 and 20-22 by dense ash emissions.

Incandescence was noted on February 22, and a smell of sulfur reported by residents of Blup Blup, 15 km north on February 16 and 22.
