【摘要】:選取唐山老震區(qū)1992—2014年的流動重力,繪制重力場測值空間變化等值線和時序變化曲線,結(jié)合唐山地區(qū)4次M≥5.0地震進行異常分析。發(fā)現(xiàn)震前有如下特征:(1)流動重力觀測資料均有較為明顯的前兆異常反應;(2)地震均發(fā)生在重力變化的"0"等值線附近。
[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,
