Three-dimensional P velocity structure in Bei**g area
A detail three-dimensional P wave velocity structure of Bei**g, Tian** and Tangshan area (BTT area) was determined by inverting local earthquake data. In total 16 048 P wave first arrival times from 16048 sh...

The S to P convert wave from the bottom of sediment basin in the near-field seismic records
From the near-field records of aftershocks of October 1989 and March 1991 Datong earthquakes, an extra phase between P and S arrivals is found. High-precision epicenter location shows that some of these record...

Determination of source-time function of intermediate and small earthquakes from empirical Green’s functions
The regularization method was used to invert the source-time function of four larger aftershocks of the Luquan, Yun-nan,M s = 6.1 earthquake of April 18, 1984. Near-field digital accelerograms wer...
