- •
Waveform inversion of SS precursors can resolve large-scale regional mantle seismic anomalies.
- •
Correction for slab dip is critical for velocity-discontinuity depth correlation analysis.
- •
Active volcanoes in northeastern China are underlain by a low velocity zone reaching 500 km depth.
- •
Temperature is the main cause of velocity and discontinuity depth changes in the western Pacific.
