A supervolcano forming north of New Zealand could spell the end of the world - but there is no need to panic, it won't happen for at least 100 million years.
Researchers from the University of Utah have warned of impending doom after discovering that two or more continent-sized piles of rock are colliding as they move at the bottom of Earth's thick mantle, 2896km beneath the Pacific Ocean near Samoa.
They said the movement could be the beginning of a vast eruption that could threaten life on earth in 100 million to 200 million years.
"What we may be detecting is the start of one of these large eruptive events that - if it ever happens - could cause very massive destruction on Earth,'' said seismologist Michael Thorne, the study's principal author and an assistant professor of geology and geophysics at the University of Utah.
"This is the type of mechanism that may generate massive plume eruptions, but on the timescale of 100 million to 200 million years from now. So don't cancel your cruises,'' he said.
