Abstract

A study of the seismograms from a seismic array in the Japanese islands offers evidence for 920-km deep seismic discontinuity in the Earth's mantle below the Tonga subduction zone. The discontinuity may be attributed to a change in the mantle's chemical content or the signature of the garnet layer of the subducted zone. The discontinuity also exists below subduction areas in the Flores and Japan seas.
