A nurse on Makira Island in Solomon Islands says people there remain on alert following a major aftershock this morning after a 7.8 magnitude earthquake on Friday morning.
Today's 6.9 tremor - one of a number of aftershocks - struck just about 8am Solomons' time.
It was much more shallow that the Friday quake at just 10 kilometres.
Hedson Taro is a nurse at South Arosi, a coastal village on Makira.
The Pacific Tsunami Warning Center's latest update says the tsunami threat for Solomon Islands, Australia, Fiji, Kiribati, Nauru, New Caledonia, Papua New Guinea and Vanuatu have largely passed.
The Center says people along coastal areas should still remain alert and exercise normal caution near the sea.
