A rift within the lute precursory response of tiltometer of Ningbo Seismological Station on Jiao Kou earthquakes 宁波台地倾斜在皎口地震活动中的前兆反应特征
It is found analytically that tiltometer records of Ningbo seismological station had anomaly responses to some extent prior to several sets of Jiaokou earthquakes since several years. 通过对宁波台地倾斜近几年来观测资料的分析,发现其在皎口几组地震事件前有不同程度的异常反应。
The data of the vertical pendulum tiltometer appeared the pulse and the step change which caused by the deformation wave. The EW direction appeared vibrate waves of the pulse to the east which is large scale of 306.280 9 × 10~ (-3)″ approximately. 垂直摆倾斜仪资料表现为形变波引起的脉冲和阶跃变化,EW向出现最大幅度约为306.2809×10-3〃的脉冲式向东振荡波,并向西出现阶跃变化;
Analysis show that SQ-70 quartz tiltometer can reflect certain anomaly informations of ground deformation. 分析认为:SQ&70石英倾斜仪反映出一定的地形变异常信息。
