| 摘 要： | 本文详细研究了1986年5月25、26日发生在山东省荣成地区的震群序列的基本特征,通过分析得出,荣成震群具有频度高、能量低、震源位置集中、频度衰减快等特点。并计算了(?)、(?)波振幅比。利用(?)波尾波估计了七个地震的平均Q值为96。初步认为荣成震群是一次频发性震群,不是前兆震群

| Abstract: | The characteristics of the earthquake swarm series occurred in Rongcheng area of Shando'ng Province on May 25 and 26, 1986 are presented in this paper. The swarm is of high and fast attenuation frequency, and of low energy and concentrated locations. The amplitude ratio of p to 5 waves is calculated and the esttimated average Q value for seven earthquakes is 96 by the tails of 5 waves. It is suggested that the swarm might occur frequently and was not a precursory one. |
