青藏块体东北缘断层气体异常与地震的关系

EARTHQUAKES AND ANOMALIES OF FAULT PRODUCT GASES ALONG THE NORTHEASTERN MARGIN OF QINGHAI-TIBET PLATE

摘要:

本文研究了青藏块体东北缘4个测点断层气体的异常变化与地震活动的关系。1992年-1993年各测点断层气组分普遍出现异常,主要表现为测值突跳、上升变化,各测点及各组份异常有明显的同步性特征。本文着重介绍了1993年10月26日托来6.0级地震前多观测,点断层气体的异常情况。最后,本文还对断层气体的场效应作了初步探讨。

Abstract:

In this paper,authors studied the relationship between seismicity anomalous changes of fault product gases at 4 measuring points along the northeastern margin of Qinghai-Tibet plate.The anomalies of fault product gas components appeared at these measuring points from 1992 to 1993,for example,sudden change and rising of the observed values.The anomalies of various components or/and at various measuring points have obvious synchronism.Authors mainly introduce the anomalies of fault gases observed at many measuring points before the Tuolai M 6.0 earthquake occurring on Oct.26,1993.At last,the field effect of fault product gases is discussed preliminarily.
