摘要
以华北地区地倾斜、地应变数字化观测为基础,研究了形变同震响应的分布特征,给出了地震面波响应延迟时间、响应幅度、同震信号持续时间(在可分辨的范围内)等特征与地震震中距离及震级之间的关系,同时还探讨了短临形变前兆与未来地震之间可能存在的关系及地震短临预测面临的科学问题。
Based on ground tilt, ground strain digital observation of North China region, author studied the distribution characteristic of deformation conseismic response, and given the relation between characteristic of earthquake surface wave response delay time, response range, conseismic signal duration and so on and distance of epicenter, earthquake magnitude. The paper discussed the relation between short-imminent deformation precursors and future earthquake and science questions of earthquake short-imminent prediction.
