摘要
本文给出了地震自然概率的定义,并对1900年以来不同震级地震的自然概率分别按年和月进行了计算,给出了以2°×2°为计算单元,1°为步长进行滑动的中国地震自然概率分布图,同时探讨了自然概率分布图在地震预报研究和评价地震预报效能中的作用。
A definition of natural probability of earthquakes is given. Natural probabilities of the earthquakes in different scales since 1990 are computed separately year by year and month by month . A scatter diagram of natural probabilities of earthquakes in China is drawn,the computing unit of which is 2°× 2°and the slipping step of which is 1°. At the same time the functions of the scatter diagram of the efficiency in earthquake predictions are also discussed.
