A tsunami measuring 0.9m (3ft) subsequently hit Lata in the far eastern Solomons.
A number of homes are reported to have been damaged in the area.
Reports suggested that the worst of the damage was expected on the western side of a point on the north-west of the island, with one report putting the height of two waves there at 1.5m.
"The wave went 500m inland, and at this stage I was told that three villages were basically damaged," Robert Iroga, press secretary to the Solomons prime minister, told the BBC, referring to three villages west of Lata.
"Houses were brought down, and the authorities were unable to ascertain as to what the damage was like because they were also running up to the mountains, up to the hills."
