Geothermal Dynamic Change of Power Function Style and Earthquake Prediction

一、引言地热在地震孕育过程中的作用和震前地热的动态异常变化,越来越引起国内外一些学者的注意,并相继开展了一些观测和研究工作。由于以往地热动态观测的精度较低,观测不够连续,难以获得进行深入研究所必须的信息。近些年来,有的国家在地热动态观测和研究方面取得了一定的进展,但所取得的具有前兆意义的地热变化信息和震例不多。自1984年开始,以地热前兆观测。

This paper summarized the precursory characteristics of a few times high precision geothermal dynamic anomalous changes. Comparing the change with earthquake case analyse, we drew the conclusion that the variation patterns are all rising tempreture anomaly of power function type. We have further discussed the empirical relations between characteristic parameters of the geothermal anomaly and occurence time and magnitude with the corresponding earthquake. Preliminary test indicated that the geothermal dynamic change of the power function style is a typical precursory anomaly, and the empirical formula would contribute to the earthquake prediction of the imminence and short-period.
