Lau Basin
Approximate surface projection on Pacific Ocean of Lau Basin. Spreading centers are shown in yellow. Clicking on map allows enlargement and mouse-over of features.
The Lau Basin is a back-arc basin (also addressed as "interarc basin"[1]) at the Australian-Pacific plate boundary. It is formed by the Pacific plate subducting under the Australian plate. The Tonga-Kermadec Ridge, a frontal arc, and the Lau-Colville Ridge, a remnant arc, sit to the eastern and western sides of the basin, respectively.[2] The basin has a raised transition area to the south where it joins the Havre Trough.
