Havre- world’s largest deep ocean volcanic eruption

Researchers have found that the world’s largest deep ocean volcanic eruption happened in New Zealand. Named as Havre, the deep ocean volcanic eruption was first discovered in 2002. A solidified volcanic rock known as pumice raft – 400 square kilometres in size – found floating in the ocean near New Zealand in 2012 showed that underwater eruption had occurred.

The eruption involved 14 aligned vents causing a ‘massive rupture’. “When this rock was produced by the volcano, it rose through the water column onto the sea surfaced and then it was dispersed by wind and sea currents.
