水化前兆异常网络及唐山地震水化前兆异常分布特征的初步讨论
A PRELIMINARY STUDY OF HYDROCHEMICAL PRECURSORY AMOMALIES NETWORK AND THE CHARACTERISTICS OF HYDROCHEMICAL PRECURSORY ANOMALIES DISTRIBUTION OF THE TANGSHAN EARTHQUAKE
-
摘要: 水化学异常点的平面分布呈网络状,与地震活动图象类似。唐山地震的水化异常发生在北东或北西向的前兆迹线上,并呈现阶段性,水化异常指示了某些断裂在地震前后有过活动。Abstract: The plane distribution of hydrochemical anomalies is like a network in shape and similar to seismic actve pattern.The bydrochemical anomalies of Tangshan earthquake occurred along a northestern or northwastern precusory trace, and showed stagcs.The hydrochemical anomalies showed that some faults had activities before and after the carthquake.
