| 摘 要： | 考虑到新疆地震台网分布不均匀的情况,尝试利用单台的宽频带波形资料进行辐射能量的测定。选用新疆喀什地震台记录的南天山西段中小地震宽频带波形资料,分析地震波形横向分量上的SH波及其后续震相,对每个地震进行辐射花样因子的校正。品质因子Q采用Brune的ω-2衰减模型,用补偿谱的方法试错得到,最后所得结果与新疆地震目录ML震级进行了对比分析,二者具有较好的一致性。

| Abstract: | Due to the sparse distribution of seismic stations in Xinjiang,we try to use broadband waveform data of a single station to estimate radiated energy.We choose the broadband waveform data of small-medium earthquakes recorded by Kashi seismic station in western of south Tianshan mountain,analyze the SH wave and latter wave in the seismic map,use the correction of the azimuth-dependence of radiation pattern,Q-value obtained by Brune omega square attenuation source model to obtain the result.compare the result and M_L magnitude,we find they are coherence. |
