| 10. | The sequence and activity characteristics of shuikou reservoir induced earthquake are analyzed with several methods , such as probabilistic evaluation , comprehensive effect parameter e evaluation , two - step comprehensive fuzzy evaluation , the maximum magnitude of historical earthquakes evaluation , etc . . the results show that the shuikou m ( subscript l ) 4 . 1 earthquake on april 21 , 1996 is a main - earthquake , and from now on , the possibility occuring m ( subscript l ) > 3 induced earthquake in shuikou reservoir area is low
摘要应用概率法、综合影响参数预测法、两级模糊评判法、古登堡里克特公式外推预测法等对水口水库诱发地震序列以及活动特征进行了研究，认为： 1996年4月21日发生的m (下标l ) 4 . 1地震为水口水库诱发地震主震，今后库区发生大于3级以上诱发地震的可能性较小。 |
