【摘要】：分別對(duì)蒼梧M_S5.4地震震前的梧州臺(tái)和呼圖壁M_S6.2地震震前的庫(kù)爾勒臺(tái)連續(xù)重力觀測(cè)數(shù)據(jù)進(jìn)行分析研究。結(jié)果表明,2次地震前梧州臺(tái)和庫(kù)爾勒臺(tái)分別觀測(cè)到10個(gè)月和7個(gè)月左右的重力非潮汐持續(xù)性上升變化,月均變化速度分別為5.0μGal/月和5.1μGal/月,累計(jì)變化分別約為50μGal和35μGal。經(jīng)現(xiàn)場(chǎng)核實(shí)和理論計(jì)算排除環(huán)境干擾影響,認(rèn)為2次地震震前數(shù)月的重力非潮汐持續(xù)上升變化與孕震過(guò)程有關(guān),可為構(gòu)建連續(xù)重力觀測(cè)地震預(yù)測(cè)指標(biāo)體系提供重要參考。
[Abstract]:The continuous gravity observation data of the Wuzhou station before the Cangwu M_S5.4 earthquake and the Kuerle station before the Hutubi M_S6.2 earthquake were analyzed and studied respectively. The results show that the variation of gravity nontidal persistence is observed in Wuzhou station and Korla station for 10 months and 7 months before the two earthquakes. The average monthly variation rate is 5.0 渭 Gal/ month and 5.1 渭 Gal/ month respectively, and the accumulative variation is about 50 渭 Gal and 35 渭 Gal, respectively. By field verification and theoretical calculation, it is considered that the continuous rise of gravity non-tide in the months before the two earthquakes is related to the seismogenic process, which can provide an important reference for the establishment of the earthquake prediction index system of continuous gravity observation.
