More details have emerged about a strong earthquake which struck late this morning off Papua New Guinea's Bougainville Island.
Initial reports centred the quake in neighbouring Solomon Islands but the United States Geological Survey says its epicentre was about 62 kilometres to the southwest of Panguna, which is in the central part of the island.
There was no tsunami warning.
Last weekend Bougainville experienced two major quakes - the strongest - 7 point 6 - claimed two lives and wrecked several dozen houses around Buin in the island's south.
Other quakes in the region around Makira, to the southeast of the Solomons' capital Honiara, sparked tsunami alerts in both countries and in Vanuatu last Sunday.
There was also a strong earthquake last night in Temotu, the most eastern of the Solomons' provinces, and the site of a destructive tsunami in February last year.
