通过近年来地震地质、卫星照片解析和大量钻探和物探工作发现,关中平原区之下广泛发育着北北东向构造形迹,是华北区新华夏构造体系的组成部分,为一个现今很活跃的构造体系。它改造先期生成的结构面、影响和控制地貌水系的发展、牵制着地震活动和地热异常区的分布。它的小震活动与华北区新华夏系构造的强震活动相呼应,可能成为现今华北区强震发生的信号之一。
Through the seismic geology, satellite photo analysis and drilling and geophysical exploration in recent years, it is found that the north-north-trending northeast structural pattern is extensively developed under the Guanzhong Plain and is an integral part of the Neo-Huaxia structural system in North China. system. It rebuilds the previously formed structural planes, influences and controls the development of the geomorphic water system and controls the distribution of seismic activity and geothermal anomalous regions. Its small earthquakes echoes with the strong earthquakes in the North China area and may be one of the signals of strong earthquakes in North China.
