Seismic scatterers in the lower mantle near subduction zones
S Kaneshima - Geophysical Journal International, 2019 - academic.oup.com
We investigate the global distribution of S-to-P scatterers in the shallow to mid-lower mantle
beneath subduction zones, where deep seismicity extends down to the bottom of the upper …
