泰安地震台钻孔应变固体潮畸变的分析探讨

ANALYSIS ON THE ABERRANCE OF SOLID TIDE FROM BOREHOLE STRAIN IN TAIAN SEISMOSTATION

摘要: 通过对泰安地震台多年应变观测资料的分析,探讨了地震发生时的同震变化以及地震前后固体潮异常变化过程,结合全国其他台站观测到的典型震例,分析了地震孕育、发生过程中应变固体潮的趋势性异常及畸变等各种异常现象,得出了应变固体潮的异常变化在地震监测预报中的作用。

Abstract: Through analysis to the strain data in Taian Seismostation, the coseismic effect and aberrance of solid tide before and after earthquake are discussed.Based the typical earthquake examples recorded by other stations, the characteristic of solid tide anomalies from strain data is analyzed.
