The North Plateau is small and almost separated from the rest of the Manihiki Plateau. [4] The High Plateau is the largest part of Manihiki covering 400,000 km 2 (150,000 sq mi) above 4000 m. The second largest part is the Western Plateaus covering 250,000 km 2 (97,000 sq mi) above 5000 m and reaching 3,500–4,000 m (11,500–13,100 ft) below ...
The Shatsky Rise is Earth's third largest oceanic plateau, [1] (after Ontong Java and Kerguelen) located in the north-west Pacific Ocean 1,500 km (930 mi) east of Japan.It is one of a series of Pacific Cretaceous large igneous provinces (LIPs) together with Hess Rise, Magellan Rise, and Ontong Java-Manihiki-Hikurangi.

Manihiki is an atoll in the northern group of the Cook Islands known informally as the "Island of Pearls". It is located in the Northern Cook Island chain , approximately 1,299 kilometres (807 mi) north of the capital island of Rarotonga , making it one of the most remote inhabitations in the Pacific Ocean .
The Tongareva triple junction, also called the Pacific-Farallon-Phoenix triple junction, was a geologic triple junction in the southwestern Pacific Basin where three tectonic plates met: the Pacific plate, the Farallon plate, and the Phoenix plate.
Ontong Java–Manihiki–Hikurangi Plateau: 121 Southwest Pacific Ocean 59–77 [n 5] Largest igneous body on Earth, later split into three widely separated oceanic plateaus, with a fourth component perhaps now accreted onto South America. Possibly linked to the Louisville hotspot. [49] [50] [51] Kerguelen Plateau–Broken Ridge 112

The Ontong Java Plateau (OJP) is a massive oceanic plateau located in the southwestern Pacific Ocean, north of the Solomon Islands. The OJP was formed around 116 million years ago (Ma), [ 1 ] with a much smaller volcanic event around 90 Ma.
The Hikurangi Plateau is an oceanic plateau in the South Pacific Ocean east of the North Island of New Zealand. It is part of a large igneous province (LIP) together with Manihiki and Ontong Java , now located 3,000 km (1,900 mi) and 3,500 km (2,200 mi) north of Hikurangi respectively. [ 2 ]
