1995年广东丰顺4.7级地震影响场及发震构造

根据实地调查初步认为，1995年11月12日广东丰顺ML4．7级地震以震级较低但破坏显著；具双极震区；震源深度大；宏观影响场分布与东西向断裂关系密切为其特征。地震发生在东西向和北东向断裂交汇并推断有北西向断裂穿越的地区。五华-丰良东西向断裂及河源-丰顺东西向断裂的东段是这次地震的主要发震断层。

INFLUENCE FIELD AND SEISMOGENIC STRUCTURE OF THE M_L4. 7 EARTHQUAKE OF FENGSHUN,GUANGDONG IN 1995

Based on the investigation upon the spot, the features of the ML4. 7 earthquake of Fengshun,Guangdong on November 12, 1995 are recognized primarily that the magnitude was lower but the destroy was notable; there were two double meizoseismal areas; focal depth was deeper; macro seismic influence fields distribution was closely interrelated with the faults in the direction of EW. The earthquake occurred in the area where the faults of EW and NE meet and there are faults of NW through probably. The Wuhua -Fengliang and Heyuan-Fengshun faults in direction of EW were the main active faults for thes earthquake.
