摘要

以震报震是我们测震学预报地震方法中的一种。各个区域每年发生的小地震事件较多,了解区域小震与小震之间的联系规律,对于今后发生的地震,我们可以通过近期发生的地震,找出未来应力变化的区域,对潜在震源区提前做出预判,也为今后大震发生找出点研究线索。本文通过对区域直达纵波走时的变化来研究地下应力的变化,从而了解区域地震与地震之间的活动规律。
The prediction of earthquake by earthquake is a basic earthquake prediction method.Since many small earthquakes occurred in each region every year,study on the relation rules among the small earthquakes is meaningful for the future earthquake prediction.We can get across the stress changes by the recent earthquakes,make a prediction for the potential seismic areas,and find out the study data for the future large earthquakes.In this paper,based on travel time changes of the the regional direct P-wave,the stress changes are studied.Furthermore,we can get across the activity rules between regional earthquakes and earthquakes.
