AT the Tonga trench, old Pacific sea floor subducts at a rapid rate below the Indo-Australia plate, generating most of the world's deep earthquakes (focal depth >300 km)1,2 and producing a deep slab of former oceanic lithosphere. The seismogenic part of the slab has been mapped in detail3,4, but its fate has remained enigmatic. Here I present evidence from seismic tomography that the Pacific plate descends deep into the Earth's mantle along a trajectory that is more complex than previously… CONTINUE READING
