新疆某些地震前地下水动态异常特征的分析

ANALYSIS OF ABNORMAL FEATURES TO THE DYNAMIC STATE OF GROUNDWATER BEFORE SOME EARTHQUAKES IN XINJIANG REGION

摘要:

本文在清理乌鲁木齐小区域井网地下水位资料和新疆某些油井动态资料的基础上,通过对震例的分析,探讨了本区地震前地下水动态异常的基本特征。认为,地震前地下水动态短临异常是明显的;异常仅仅出现在震源附近的有限区域;异常形态大致可以分为两种类型,即下降型和喷涌型。最后,对在地震孕育过程中与地下水异常有关的几个问题进行了初步的讨论。

Abstract:

In this paper the authors have rearranged and analysed the data of groundwater level and some oil wells in Xinjiang Region and discussed the abnormalfeatures of groundwater dynamic state before moderate strong earthquakes. We think that in this region the short-term and imminent precursors of groundwater level are conspicuous. But such anomalies can only be observed in the limited area close to the anomalies of earthquake source, and they are roughly divided into twot ypes, the descending and the spouting Afew problems relating to the groundwater in the process of earthquake preparing are under discussion as well.
