摘要: 应用泊松模型的极值分布对华北地区的地震活动趋势进行估计和分析,结果表明,2008年前华北地区发生6级以上地震的危险性较大;2005年地震活动短期内可能还会持续目前较弱的态势,但未来1~2年内华北地区地震活动很有可能明显增强。Abstract: The tendency of earthquakes activity in North China is estimated with the extremum distribution of Poisson model.The results show that the risk of over 6 earthquakes is relatively heavy.Seismic activity will keep weak in a short period of 2005,but will increase in the next 1~2 years in North China area.
