摘要

１９９２年１１月２６日在福建连城发生了５．０级地震，宏观震中位于黄地－赖源－带（１１６°５７′Ｅ，２５°３２′Ｎ），震中烈度Ⅵ度强，震源深度７－８ｋｍ。极震区等震线呈椭圆形，长轴方向为ＮＥ，与震中区的黄地－梅村头断裂展布方向基本一致，余震沿该断裂分布，并自ＮＥ向ＳＷ方向迁移。黄地－梅村头断裂可能是这次地震的发震构造。
A M5.0 earthquake occurred in Liancheng on Nov.26,1992.The macroscopic epicenteris situated between Huangdi and Laiyuan(116°57′E,25°32′N),epicentral intensity is Ⅵ￣+,focal depth is about 7.5 km,The isoseismal map of meizoseismal region shows oblong,Itslong-axis strike is NNE,which is same as the that of the Huangdi-Meicuntou fault in epicen-tral area. The aftershocks were distributed along the fault and migrated from NE to SW. Tt isconsidered that the Huangdi-Meicuntou fault might be seismogenic structure of this earth-quake.
