The 6 February 2013 magnitude 8.0 Mw Santa Cruz Islands, Solomon Islands earthquake (10.738 S, 165.138 E, depth 29 km) generated a tsunami that was observed all over the Pacific region and caused deaths and damage locally. According to news reports, the worst damage was observed approximately 75 km from the epicenter on the western part of Ndeni (Ndeno) Island where 1.5 meter waves caused 9 deaths, destroyed 460 homes across 5 villages, and damaged the airport at Lata. In 2007, a magnitude 8.1 Mw earthquake located approximately 900 km from this event generated a tsunami that caused 52 deaths.
According to the USGS, the 6 February 2013 earthquake occurred as a result of shallow thrust faulting on or near the plate boundary interface between the Australia and Pacific plates. In the region of this earthquake, the Australia plate converges with and subducts beneath the Pacific plate, moving towards the east-northeast at a rate of approximately 94 mm/yr.

On 6 February 2013, a powerful M8.0 earthquake occurred at 01:12 UTC off the Santa Cruz Islands, Solomons due to shallow thrust faulting at a depth of 28 km on or near the plate boundary interface between the Australia and Pacific plates. The M8 earthquake generated a tsunami that was recorded on sea level gauges around the Pacific. The largest wave of 1 m amplitude was recorded at Lata Wharf located about 50 km from the epicenter. Over the month leading up to the event, there had been dozens of earthquakes in the epicentral region, 7 of which were greater than M6. There were also two greater than M6 aftershocks.
