The 2013 Solomon Islands earthquake struck northeast of Australia on 6 February with a moment magnitude of 8.0. Its epicenter was the Solomon Islands, at the boundaries of the Australian and Pacific tectonic plates, causing local evacuations and a tsunami of and killing at least 9 people. == Tectonic setting ==
The Santa Cruz and Solomon Islands are located on the plate boundary between the Australian and Pacific plate. This highly seismic region has “near 90° bend in the boundary…"〔(【引用サイトリンク】 title=The February 6, 2013 Mw 8.0 Santa Cruz Islands earthquake and tsunami )〕 This area experiences much plate movement as the Santa Cruz Island “has upper plate strike-slip and normal faulting, plate boundary under-thrusting, outer rise extensional faulting, and intraplate faulting” and the Solomon Islands are located on the subduction zone of the two boundaries.〔 On February 6, 2013, the largest under-thrusting earthquake ever to be recorded in that area caused a tsunami and both were destructive to the area. Major villages on both groups of islands, Lata and Nendö were destroyed and at least 724 homes were confirmed as damaged.
