- Abstract:
- According to the characteristics of the tectonic fault and stress field orientation in the Yishu fault zone and its adjacent area,we divided the study area into four sub-areas. Then we calculated the Qc value of ML≥2.0 earthquakes in each sub-areas from 2010 to 2017 by the improved Qc-value measurement method,and studied the temporal and spatial distribution characteristics. The results show that:①The Qc value of the coda wave(Qc value at 1 Hz)of Yishu fault changes a little overall,but the segmentation characteristics is significant,that is the average Qc value(34.95)in Laizhou Bay and its adjacent sea areas is significantly higher than that of other sections. The average Qc value of the Weifang-Mengtuan section(23.22),Xinyi-Suqian section(21.12)is relatively low; ②The spatial distribution of the coda wave Qc value is closely related to the structural characteristics of the regional crustal medium,which clearly revealed the attributionof Yishu fault as the structural boundary zone.
