摘要

Based on the analysis of small local earthquake waveforms, the spectral structure of velocity inhomogeneity in Changbaishan Tianchi volcano area was studied by the peak delay time of S-wave envelope broadening method. The results show that the shallow crust medium of Tianchi volcano,Changbaishan area presents strong inhomogeneity and frequency dependence.
