【摘要】 计算了福建1990~2004年的地倾斜EW和NS两分量的固体潮潮汐因子,绘制了动态组合的3种特征量(扩容、剪切应变、介质各向异性)全程时序曲线图,并分析了与中强地震的关系。结果表明:在福建沿海,海潮是决定倾斜固体潮特征的主要因素;福建发生4.5级以上中强地震或台湾发生7级以上强烈地震时,地倾斜固体潮潮汐因子动态组合特征量与之有较好的对应关系。更多还原

【Abstract】 The tidal factors from the EW and NS components of ground tilt in Fujian from 1990 to 2004 are calculated. The full-time plots for the characteristic quantities (dilatancy, shearing strain, media anisotropy) are drawn and their relations with mid-strong earthquake are analyzed. The results show that the ocean tide is a main factor to determine the characteristics of tilt tide in the shore area of Fujian and the dynamic combination characteristic quantities of tilt tide correspond to Fujian earthquake (M>4.5) or Taiwan earthquake (M>7.0) well.更多还原
