摘要
为了满足地磁无量纲参数地震短期预报及多参数综合预报的需要 ,分析研究了地磁无量纲参数 Bij方法 ,取得了 1995年 10月 6日唐山 5.0级地震 Bij异常短期 (三个月 )追踪图象。依据 Bij异常 (测点数量、幅度、空间分布的大小和方向 )时空演化过程和演变特征 。
In order to meet the need of earthquake short-term prediction with geomagnetic non dimensional parameter and multi-comprehensive prediction,we studied geomagnetic non dimensional parameter B i,j method,and obtained the short-term(3 months)B i,j tracing image before and after the Tangsan Ms5.6 earthquake on October 6,1995.Based on B i,j anomalies' time-space evolutionary process and character(number of station,amplitude,the expansion and direction of spatial distribution),we can make trial of earthquake short term prediction.
