【摘要】:选取唐山老震区1992—2014年的流动重力,绘制重力场测值空间变化等值线和时序变化曲线,结合唐山地区4次M≥5.0地震进行异常分析。发现震前有如下特征:(1)流动重力观测资料均有较为明显的前兆异常反应;(2)地震均发生在重力变化的"0"等值线附近。
[Abstract]:This paper selects the flowing gravity of Tangshan old seismic area from 1992 to 2014, draws the isoline of spatial variation of gravity field values and the curve of time series variation, and analyzes the anomalies of 4 earthquakes with M 鈮,
