【摘要】 从吉林深震的形成与板块构造活动的关系入手,介绍了深震与吉林省区域构造活动背景的联系。利用测震学活动性指标,讨论了发震前后区域地震能量时空变化的特点,并结合对前兆资料的分析,得出了深震前后区域地震能量的累积与释放的特点。本文试图阐明异同,探讨机制,以期对地震活动规律的研究有所帮助。更多还原

【Abstract】 In this paper, the relationship between deep earthquake and the regional tectonic activity background in Jilin Province was introduced based on the research about the relationship between formation of deep earthquakes and plate tectonic activity. The authors discuss the temporal and spatial variation characteristics on regional seismic energy before and after earthquakes with seismic activity index and analyze the accumulative and releasing (emissive) characteristics of regional seismic energy with the premonitory information. Demonstrating the difference and discussing the mechanism, the authors expect the results are helpful for research on the law of seismic activity in Jilin province.更多还原
