Presentation Transcript

  1. Waveform modeling of core phases at very long distances (150o +) Model PKP-BC & PKP-Cdiff near the C-caustic (150o-160o) to constrain seismic parameters such as velocity, its gradient and intrinsic attenuation just above and at the inner core boundary Model selected phases PKIKP, PKIIKP etc. at near antipodal (180o) distances to constrain seismic velocity, texture & intrinsic attenuation of the shallow and deep inner core.
