大同地震序列的尾波Q值变化特征研究

Abstract

Abstract: Based on the seismic recording data of the Telemetric Seismic Network of Datong from 1990~2000, the variation characteristics of seismic code Q value of Datong earthquake sequence with time, especially the short-term variation characteristics before moderate strong earthquakes are systematically analyzed. The results indicate that the code Q value of earth frequency show low value before several moderate strong earthquakes and show the anomaly with Datong seismic condition “window” synchronously.

Key words: code Q value, earthquake sequence, Variation Characteristics, Datong area
