本文研究了我国大陆地区五级以上地震的时间间隔分布情况,发现我国大陆M_S≥5.0地震的时间间隔ΔT与其频次N_(ΔT)之间存在以下关系式:lgN_(ΔT)=2.14-0.15·ΔT本文还讨论了我国大陆出现长期无五级以上地震后,是否将有七级地震的问题。
This paper studies the time interval distribution of earthquakes with magnitude more than five in mainland China and finds that there exists the following relationship between the time interval ΔT and the frequency N_ (ΔT) of M_S≥5.0 earthquakes in China: lgN_ (ΔT) = 2.14-0.15 · ΔT This article also discusses whether there will be a magnitude seven earthquake after the occurrence of a long-term earthquake of magnitude five or more in China’s mainland.
