Basically two different methods have been used to determine simultaneously the intrinsic source parameters and the source location and/or station residuals. One is a linearized least-squares method, the other method uses a nonlinear correlation procedure. The two methods have been applied here to the same long-period (~ 25 s) GDSN data from a set of earthquakes under the Tibetan plateau. In these circumstances it is found that the nonlinear correlation method leads to more stable and reliable results, which can be interpreted in a geophysically meaningful way. The results show that all of the events are shallow focus (<= 10 km) and in accordance with east-west extensional tectonics. The time delays obtained by the correlation method were used to infer S-P residuals associated with the near-source structure. Although the number of data is rather small, they do suggest a trend to high residuals in Northern Tibet (4.6 and 4.8 s relative to J-B times), corroborating earlier findings.
