Giant blobs deep inside Earth are 'evolving by themselves'

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

These blobs, located beneath the Pacific Ocean and Africa, are characterized by seismic waves that travel 1% to…

A new investigation has revealed that the giant mantle regions where seismic waves slow down may have formed from the sublet oceanic crust. Now researchers believe they know where the two giant structures in the middle layer of the Earth come from, and they are a “different pair.” These strange regions of the Earth are [...]
