【摘要】 本文运用地震频度衰减系数h值,震群能量释放均匀度u值、震群归一化熵值K等地震活动参数的统计分析,研究了长汀震群以及闽赣地区其它小震群的殊征,认为长汀震群是一次无前兆性质的正常地震活动,而龙南震群是一次前兆性震群。更多还原

【Abstract】 In this paper, by using the statistics and analysis of the earthquake activity factors, including the seismic frequency attenuation coefficient H values, the average U values of earthquake energy release, and earthquake swarm normalized entropy K values etc, the characteristics of the Changting earthquake swarms and other swarms in Fujian and Jiangxi has been studied. It has determined that the Changting earthquake swarm is a normal earthquake activity of no earthquake premonetory, while the Longnan earthquake swarm is a swarm that has premonetory.更多还原
