THE ANALYSIS OF SUDDEN CHANGE OF EARTHQUAKE TIME SEQUENCE

摘要: 采用Mann-kendall非参数方法检验了陕西及邻省的历史及现今地震序列,发现存在若干突变点,在其前后地震频次和强度发生非连续时间变化,这个研究有助于地震演变规律认识。

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