The quake struck at a depth of about 30 kilometres with an epicentre 40 kilometres south-west of Kira Kira, on Makira Island, and 224 kilometres south-east of the capital, Honiara, at 4.30 pm (local time), the USGS said. Like much of the Pacific, the Solomons regularly experience earthquakes, most recently a 6.8 magnitude tremor in April, without a tsuanmi or reports of damage.
A string of tremors rocked the western Solomon Islands in January, with the largest of 7.2 causing a tsunami estimated at nearly 2.5 metres. About 1,000 people - almost a third of the population - are believed to have been left homeless on Rendova island due to earthquake and tsunami damage."
