| Abstract: | At Beijing time 7:49 on April 14,2010,an earthquake of magnitude 7.1 occurred in Yushu county,Tibetan autonomous prefecture in Qinghai Province.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,... |
