摘要
出现在青海共和6.9级地震震区的地壳垂直形变异常,在震后一年多的时间内不仅依然存在,而且还有明显增强。分析表明,它很可能是一种长趋势的形变异常,并可能以形变峰的形式逐渐向北东推移,在适合的构造条件下发震。
The vertical deformation anomaly appeared before the Gonghe earthquake (M=6.9) not only does not disappear after more than one year of the Gonghe earthquake, but also incresing clear. The analyses show that the tendency is probably a long—term deformation anomaly and moving gradual in the forms of deformation—peak towards NE direction, and finally, leads to earthquake if the structure condotions are appropriate.
