| Abstract: | With the enhancement of observation capabilities and the improvement of observation means, the research of Q value reflecting the earth medium characteristics continues to deepen and develop. In this paper, based on the digital network seismic waveform of Shandong Province, we calculate the Q the pulse broadening method values of Qingdao earthquake swarm in 2003 and 2004 through in the time domain. Two different methods getting the first hail P-wave pulse are compared. Finally, we ening method and calculation results and sum up the applicable conditions of the pulse broadobtain the Q values in Qingdao and Jiaodong region. |
