Experts are baffled by structures under Pacific that shouldn't exist

Scientists at ETH Zurich and Caltech have found massive structures deep beneath the Pacific Ocean that 'shouldn't exist' Seismic activity can be detected along the tectonic plate's borders, where the plates rub up against each other.

But in the ancient past, large plates have since disappeared into Earth 's mantle by means of 'subduction' This is the geologic process in which one edge of one plate is forced below the edge of another and over time an entire plate can be lost.

The findings challenge 'our current understanding of how the Earth works'.
