Regional Seismic Event Location in Asia


Propagation Path Corrections (PPCs) have been constructed for 49 NEIC/ISC stations and 6 PIDC stations. Use of these PPCs dramatically improves seismic event locations at Lop Nor. However, additional ground truth is required to test the applicability of these PPCs at other locations Pn tomography is being explored as a means of predicting PPCs in regions lacking data.
