Abstract We show evidence that materials with significantly different elastic properties are juxtaposed in the lower mantle immediately below the subducting Tonga slab (depths ⩽ 1000 km), like the anomalies preferentially located beneath the lower mantle slabs at other Pacific subduction zones ( Kaneshima, 2009 ). Array analyses of wave form data of short period seismic networks at western United States and Japan for deep earthquakes at the Tonga slab reveal S-to-P scatterers with a size less… CONTINUE READING
