Remnant of world’s largest ‘lava lamp blob’ discovered off

About 120 million years in the past, a gargantuan blob of sizzling rock indifferent from the sting of Earth’s core and oozed up towards the planet’s floor. Right this moment, an enormous chunk of that blob — or “superplume,” as geologists name it — could also be lurking off the coast of New Zealand, new analysis suggests.

In a research printed Could 27 within the journal Science Advances, researchers measured the velocity of seismic waves touring by means of a layer of Earth known as the mantle that sits between the planet’s crust and outer core. They centered on Hikurangi Plateau — an unlimited, triangle-shaped chunk of volcanic rock positioned about 2,000 miles (3,200 kilometers) beneath the highest of the South Pacific Ocean, simply off the coast of New Zealand’s North Island. The staff discovered a match between the seismic waves touring by means of that chunk and people touring by means of two different close by volcanic constructions.
