| 摘 要： | 利用青海地区1900年以来5级以上强震目录探讨了省内各地震带地震活动的基本状态,结合累积应变能释放现象讨论了各地震带现今地震活动所处的状态。结果显示,青海地区4个地震带强震活动存在明显的平静与活跃的交替特征,这是普遍的宏观规律,但平静与活跃的特点具有差异性。伴随各地震带地震活动状态的不同,其累积应变能释放呈现加速或减速的特征。

| Abstract: | Basic states of strong earthquakes with Ms≥5. 0 in seismic belts in Qinghai region since 1900 have been analyzed. The various states of seismic tectonic activities are discussed according to the strain accumulation release phenomena. The results show that the characteristics of active and calm periods for moderatestrong earthquakes in each belts are different. The strain accumulation release shows acceleration or deceleration with the different states of seismic-belts. |
