【摘要】 系统整理分析了1983~2008年乾陵台地倾斜仪记录到的暂态异常图像,发现其与周围4000km以内6.5级以上强震有一定的对应关系。异常图像以渐变、突变阶跃、畸变及脉动为主要特征,异常出现时间为震前0~40天,主要集中在震前4天。更多还原

【Abstract】 The momentary abnormal state patterns in 1983~2008 years of the ground incline in Qianling seismic station are analyzed,and the results show that there are related between the anomalies and strong earthquakes with Ms≥6.5 in 4 000km.And the anomalous characteristics are mainly presented by the gradient,abrupt change order,distorted and systolic.The anomalous time will be appeared in 0～40 days before earthquakes,mainly focused in 4 days before the events.更多还原
