摘要
在中国大陆2001年以来发生的数次5级以上地震前,山西侯马数字化形变台的波形记录发生了明显变化。本文就此进行了初步分析,认为强震前的预滑移可能产生这种长周期的形变波,它们对大震预报有一定意义。
Before several M5.0 earthquakes from 2001, the wave recording data of the defomation digital observation show the clear changes in seismic station of Houma, Shanxi Province. In this paper we analyze these data and find that the deformation wave of long period comes from pre-movement before a strong earthquake. These changes data are help to the earthquake prediction.
