The local observatory Observatoire Volcanologique de Goma (OVG) reported that the effusive eruption at the volcano started to wane on 21 May.
The drop in activity has been detected at Rumangabo monitoring station.
The lava flow, spilling out onto the western flank and fed from the lava lake outlet channel, slowed down its pace and gently began solidifying, i.e. making a crust on the lava flow surface.
