摘　　要：根据地震现场宏观烈度调查资料 ,介绍了 1999年 3月 2 5日广东河源市ML4 7级地震的影响场特征 ,与其他相近震级地震作了比较 ,发现这次地震的Ⅵ度极震区明显偏小 ,并认为这次地震与NNE和近EW向的断裂活动有密切关系。Based on the information of the macroseismic survey, the features of macroseismic influence field of the M L4 7 earthquake on Mar 25, 1999 in Heyuan, Guangdong are introduced. The earthquake is compared with the other shocks which the magnitude is similar. It is discovered that the meizoseismal area of intensity 6 was small obviously, and we considered that this quake was in close relationship with activity of the faults which are NNE-trending and nearly EW-trending.
