Improving Regional Seismic Event Location in China


Summary

Using modified Bayesian kriging, we have calculated PPCs for 74 regional stations around China, including 6 IMS stations. Surfaces are checked using cross-validation and ground truth from Lop Nor, Balapan, and Tibet. The use of PPC surfaces improves location accuracy when applied to regional location problems. Teleseismic locations are relatively unaffected when regional PPCs are used in the solution.
