摘要
研究了华北中强地震前 3年Morishita播散指数的空间演化 ,发现Iδ 异常几乎都是首先在远离震中的地方出现 ,并逐步向未来震中集中 ,这种规律可为地震的地点预报提供重要信息。
After studding spatial evolvement of Morishita spread index, we found the anomaly of I δ which almost showed where were far distance to the epicenter after three years occurred moderate strong earthquakes in large North China, and gradually concentrated to the epicenter of future earthquake. This pattern may be an important information for predicting the location of future earthquake.
