Location of the Ontong Java Plateau in the Pacific Ocean

The Ontong Java Plateau (OJP) is a huge oceanic plateau in the southwestern Pacific Ocean, north of the Solomon Islands. The OJP was formed around 120 million years ago.^[1] When eruption of lava ended, the Ontong plateau covered 1% of Earth's surface. It had a volume of 80 million km³ (19 million cu mi) of basaltic magma.^[2]

This Ontong Java event was the largest volcanic event of the past 200 million years. Its magma production was several times larger than the Deccan Traps.^[3] The smooth surface of the OJP is punctuated by seamounts such as the Ontong Java Atoll, one of the largest atolls in the world.^[4][5]
