Introduction

Waveform character varies dramatically within tectonically complex regions such as China.


Correction for path effects will reduce scatter in discrimination studies, refine regional magnitudes and help to define geophysical provinces.


Previous work demonstrates that a combination of waveguide and interpolation methods leads to effective path effect prediction. The combination yields accurate prediction in active regions and more effective extrapolation beyond. Tomographic models can be used in the same manner.

Path model based on topography (after Fan and Lay, 1998) Residuals to path model, interpolated
using Bayesian Kriging (Schultz et al.,1998)
