1992年蒙古曼来6．1级地震前远场前兆特征的研究

RESEARCH ON THE CHARACTERISTICS OF FAR-FIELD PRECURSOR BEFORE THE MANLAI M6.1 EARTHQUAKE,MONGOLIA,IN 1992

本文在对１９９２年８月３１日蒙古曼来６．１级地震前远场区域（△＝３００－４５０ｋｍ）部分前兆观测资料进行分析的基础上，认为具有区域集中性和时域准同步性的异常群，可能是孕震中、短期前兆的普适性特征，并据此对地震时、空、强三要素进行了预测研究。

Based on the analysis of a portion of the far-field(△=300─450 km)precursory databefore the Manlai M 6.1 earthquake occurring in Mongolia on Aug. 31.1992,this paper putsforward that an anomaly group with regional concentration and time-domain quasi-synchro-nism will probably be a universalism chdracter of medium-term and short-term precursorsduring earthquake-pregnant process and. based on this concept.makes a reseach On the threeseismic factors of time,space and strength.
