| 摘 要： | 利用1972年1月1日—2005年12月31日云南省地震遥测台网的地震正式目录,对正式目录中的中强以上地震进行了余震删除。利用已删除余震的正式目录,分析实验场及邻区4.0~4.5级调制地震与中强地震的关系,总结历史震例得到:实验场及邻区发生4.0~4.5级调制地震,其后发生中强以上地震的可能性为81%,平均间隔时间为9.6月,而且中强震发震地点与4.0~4.5级调制地震发震地点相关性较好,平均相隔距离为85 km。

| Abstract: | Using the formal earthquake catalogue got from Yunnan seismic network from Jan.1,1972 to Dec.,31,2005,in which aftershocks have been deleted,the author studies the relationship between modulated earthquakes of M4.0~4.5 and following medium-stronger earthquakes which occurred in Western Yunnan Earthquake Prediction Test Site(WYEPTS) and its neighboring area.It is found that: there is better interrelationship between them,not only in time but also in space.The corresponding rate between modulated earthquakes and following medium-stronger earthquakes is 81%,and the average time interval between them is about 9.6 months, the average spacial distance is about 85 km.These could be helpful to earthquake prediction in this area. |
