摘要
In this paper, the Kolmogorow-Smirnov distribution test method has been used to test the distribution of the monthly number of small earthquakes on multi-scale. It was found that this number is neither normal distribution nor Possion distribution. According to computed values of kurtosis, skewness, standard deviation, the value of CV and some other statistical parameters, for example the bm parameter, the authors also analyzed the time variation of the monthly number distribution of small earthquakes before the 2010 M7.1 Yushu Earthquake.
