地震动态应力触发研究进展

Development in the Research of Seismic Dynamic Stress Triggering

本文从以下几方面阐述了近几年来地震动态应力触发的研究进展:地震动态应力触发问题的提出;地震动态应力触发存在的证据(包括地震频度图中探寻被触发震群和独立地震、数字滤波后新发现的被触发地震和形变仪器记录的同震变化和应力阶跃等);地震动态触发的研究现状和机理等。还提出了目前动态应力触发研究中存在的问题,并对其近期的发展进行了展望。

The research progress of seismic dynamic stress triggering in recent years from several aspects is expounded ： How the problems are put forward. The exist evidences of dynamic stress triggering, including seek triggered earthquake swarm or single earthquake in seismic frequency map, find new triggered earthquake by digital filter, and co-seism change and stress step recorded by strain instrument; current situation of the research; triggering mechanism and so on. Meanwhile some problems in the research are given up, and the development of seismic dynamic tress triggering research in recent future is look ahead.
