New Zealand found the world’s largest lava bubble

Under New Zealand, they found the world’s largest lava bubble. The discovery was made by scientists from the University of Victoria, their study was published in the journal Science Advances.

Volcanism is usually explained by the rise of magma in the central parts of the oceans, the immersion of lithospheric plates in the mantle, or the movement of mantle plumes to the surface.

As a result of volcanism, according to a study of scientists, the North Island arose, one of the two main islands in New Zealand. The eruption that formed the island occurred about 120 million years ago, when a gigantic stream of hot lava rock erupted from the boundary of the core and mantle, about 3 thousand km below the Earth’s surface, and quickly rose to the surface in the form of superplume.

“Very large volcanic eruptions occurred in the geological past, the largest of which was recorded in the southwestern Pacific Ocean. It occurred in the Cretaceous during the time of the dinosaurs – as a result of it formed an underwater volcanic plateau the size of a continent. Subsequently, the movement of tectonic plates violated the integrity of this plateau, and one fragment – today forming the Hikurangi plateau – went south, and now lies at the heart of the North Island”.

The plateau was formed due to the rise from the bowels of the earth of superplume – a giant bubble with lava, which froze as the temperature fell closer to the surface of the Earth.
