The shape and geometry of inclusion is an important factor which affects the precursory seismicity pattern 包体的形状和几何位置是影响强震前兆地震活动图像形态的重要因素。
The three methods to extracting the synthetic precursory anomaly and the related numerical results can be applied into the practice of the grouped - earthquake prediction in the sichuan - yunnan region 研究结果表明,在川滇地区,单个6级地震与成组强震的前兆群体异常表现有较大差异,成组强震前兆群体异常信息更为丰富。
