形变,应变短临前兆标志体系

建立各手段的前兆异常标志,从而组合各类前兆标志体系是“八五”地震短临预报攻关研究项目的重要目标之一。本文以形变,应变手段的主要研究对象,初步建立了一个形变应变短临前兆标志体系,并总结出了各种异常的判别标志,为利用系统优化理论和专家系统理论进一步研究形变应前兆系统和地震之间的关系,从而为提高中短期地震预报的水平打下了一定的基础。

SHORT-IMPENDING PRECURSOR INDEX SYSTEM FROM CRUSTAL DEFORMATION AND STRAIN DATA

Setting up the precursor abnormal indexes of various method, and then making up different kinds of precursor index system is one of important objective of earthquake prediction of the "Eighth Five-year" project in our country. As an example, a shortimpending precusor index system from crustal deformation and strain data is set up and the marks for judging various anomalies are given preliminarily. And then by using system optimization and expert system theories, the basis has been formed for further researching on the relationship between crustal deformation-strain precursor system and earthquakes and improving the standard of medium-short-term earthquake prediction.
