波速异常的区域特征

On District Features of Seismic Velocity Anomalies

摘要:

有关波速比异常预报地震的震例已有不少论述,然而就一个地区的波速异常区域特征则很少讨论。为进一步监视地震活动,做好地震预报工作,我们以甘肃及邻近地区近十年来发生的一些中强地震为例,研究了它们的时空特性,並同其它一些地区的研究结果进行比较,总结出该地区的预报经验,提出以下几点认识。

Abstract:

On the basis of observational data obtained in Gansu Province and its neighbour region, the district features of seismic velocity anomalies were investigated briefly. The results obtained may be useful for researches on the earthquake prediction in a given concrete seismically active region.
