| Abstract: | The historical and nowaday earthquake sequences in Shanxi Provimce and its adjacent provinces are checked by Mann-Kendall non-parameter method. It is found that there are a number of sudden change points; before and after them, the earthquake frequency and magnitude show non-sutcesivestep changes. This research has contributed to the cognition of earthquake evolution law. |
