| 摘 要： | 根据１９９７年１０月初全国范围内地震非均匀度（ＧＬ值）方法的空间和时间扫描结果,在内蒙古中部和华北北部地区出现的明显高值异常,提出这２个地区未来１年存在发生５￣６级地震的可能。此后在１９９７年１０月１８日和１９９８年１月１０日在上述２个异常区域分别发生了内蒙古临河Ｍｓ５．０和河北省张北－尚义Ｍｓ６．２地震。通过对这２次地震前ＧＬ值的变化过程进行了分析总结,初步提出了中强地震前ＧＬ值的变化特征。

| Abstract: | In early October 1997, based on the obviously high value anomalies in the middle part of Inner Mongolia and the northern part of North China in the result of spatial and time scanning of the seismic inhomogeneous degree (the GL value method) all over China, it was proposed that there might happen an earthquake with M=5~6 respectively in each region in the coming year. Since then, an Ms 5. 0 earthquake and an Ms 6. 2 earthquake happened in these two regions respectively. In this paper , the change processes of the GL values before the two events are discussed and the change features of the GL values before moderately strong earthquakes are concluded preliminarily to apply this method to the prediction of moderately strong earthquakes more broadly in the future. |
