摘要
北京大海坨M_L=49地震前,白家疃地热、地形变两种观测项目,同时观测记录到明显的异常变化,具有短期和短促、突发的临震异常特点,采取针对性的分析方法,结果较好,为单台多项(前兆方法)综合预报提供了震兆观测实例。
Obvious anomalies of geotherm and crust deformation were recorded at observatory Baijiatuan before the occurence of Dahaituo earthquake with magnitude M_L=4.9. The forthcoming earthquake anomalies have the characteristic of short period and suddenness. The detail analysis using corresponding method gives an example of earthquake precursor observation for comprehensive foreasting of single station.
