喀左地震台土体地应力观测映震效能分析

ANALYSIS ON KAZUO SEISMIC STATION GEOSTRESS OBSERVATION EARTHQUAKE-REFLECTING PERFORMANCE

本文通过整理喀左地震台地应力观测资料,并结合历史震例,对发生地震的时间、方位、震级与喀左地震台地应力异常特征的关系作出初步分析判断,认为喀左地震台土体应力观测对辽西及周边地区小震及中强震有很好的异常反应,有较好的映震效能,并对东北地区尤其是吉林深震有一定的异常显示。

Based on the Kazuo seismic geostress observation data,and combining the historical earthquake examples,the relationship between Kazuo seismic geostress anomalous features and the earthquake time,location,magnitude was analyzed.It was showed that the observation of soil stress in Kazuo seismic station have a very good abnormal reaction to the small and medium-strong earthquakes in western of Liaoning and circumjacent area.And it has some certain abnormal reaction to the northeastern area,especially to Jilin deep earthquakes.
