松潘地震地下水异常动态特征

On The Dynamical Characteristics Of Underground Water Anomaly During The Songpan Earthquake

摘要:

本文在综合实际资料的基础上,扼要地描述了松潘地震前后地下水异常在时间和空间上的动态特征。並根据岩石力学的基本原理,对这些特征进行了初步探讨。

Abstract:

In this Paper the dynamical characteristics of underground water an-omaly in the time and space domain before and after Songpan-pingwu ea-rthquake are briefly described on the basis of comprehensive practical da-ta.Preliminary discussion on these characteristics according to the funda-mental principles of rock mechanics is given.It is pointed out that vario-us phenomena of anomaly are related to the mechanism of anomaly form-ation in the different stages of earthquake pregnancy.It may be referential in earthquake prediction,especially the short-range forecast.
