The Lord Howe Rise is an underwater plateau that lies 800 kilometres offshore from mainland Australia. The Lord Howe Rise extends from southwest of New Caledonia to the Challenger Plateau, west of New Zealand. To the west is the Tasman Basin and to the east is the New Caledonia Basin. It has a total area of about 1,500,000 square km. Water depths are about from 1500 to 2500 metres. The Lord Howe Rise is made of continental crust that was rifted away from Eastern Australia by a mid-ocean ridge that was active from 80 to 60 million years ago. It is part of Zealandia, a much larger continent, now mostly submerged.
