A submarine eruption began on 8 May, and was ongoing as of the report issued on 12 May. The site is believed to be the same location as a submarine eruption in 1972, situated near the junction of two segments along the N margin of the South Bismarck Plate. Satellite imagery acquired on 10 May showed a large steam plume rising to 3,000 m above the eruption center. A plume of shallow sediment and discolored water approximately 9 km by 11 km in size was also observed in the satellite data, indicative of active submarine venting. The eruption was preceded by seismic activity recorded at the same location on 31 March and 25 April. Then, a small swarm consisting of 6 earthquakes was recorded on 8 May.
