从活动构造角度讨论1605年大震的“余震”地点问题

Discussion on the Location of the 'Aftershocks' of the Macroquake Occurred in 1605 from the Point of View of Active Tectonics

从重、磁场、断裂构造、地震活动以及地震影响场、发震机制等多方面分析,认为1605年琼山大震的几个6级左右“余震”置于雷州半岛东侧是与活动构造带吻合的,基本上合理,赞成1995年版《中国历史强震目录》所确定的地点。但认为这些“余震”属“地震迁移”活动性质。

By means of analysis of gravity, magnetic field, fracture structure, seismicity, seismic infection field, seismogenic mechanism and so on, it is considered that the conclusion that the location of several aftershocks with magnitude about 6 of the macroquake in 1605 was on the east side of Leizhou peninsula was reasonable and accordant with the active tectonic zone.
