在这项研究中，P波和S波衰减的频率依赖性确定的方面和在马什哈德地区。分析中使用的当地地震数据来自本研究期间在该地区安装的10个地震台站。在本研究中，使用了扩展的尾波归一化方法。分析表明，在马什哈德地区衰减的频率依赖性。从1.5 Hz时的0.01258±0.005034下降到24.0 Hz时的0.000863±0.000414，并从1.5 Hz时的0.008019±0.004359下降到24.0 Hz时的0.000352±0.000314。使用回归方法，我们发现了以下关系：
In this study, the frequency dependence of P and S waves attenuation are determined in terms of and in Mashhad area. The local seismic data used in this analysis are come from 10 seismic stations, installed in the area during this study. The extended coda normalization method has been used in this research. The analysis shows the frequency dependence of attenuation in Mashhad area. The decrease from 0.01258±0.005034 at 1.5 Hz to 0.000863±0.000414 at 24.0 Hz and decrease from 0.008019±0.004359 at 1.5 Hz to 0.000352±0.000314 at 24.0 Hz. Using the regression methods we have fined the following relations:
