| Abstract: | 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. |
