CHARACTERISTICS OF STRONG EARTHQUAKE ACTIVITY AND ITS TENDENCY ESTIMATION IN NORTHEAST AREA IN QINGHAI PROVINCE
【摘要】 2003年4月17日,德令哈西发生了Ms6 6级地震,通过分析区域强震活动的时空特征,认为该区域强震活动具有相对活跃时段和相对平静时段,在强震的相对活跃时段内,强震的发生具有一定的时空特征。
【Abstract】 An earthquake with Ms6.6 occurred in west Delingha on Apr.17,2003.Strong earthquake activities in this area exist relatively active-quiet episodes by analysing the temporal-spatial characteristics of seismicities.During the active episode,there are some temporal-spatial characteristics before strong earthquakes occurance.
