2008年前东北地震大形势研究
A study on the great situation of earthquake in Northeast China till the year of 2008
【摘要】 根据东北地区1900年以来的历史地震资料所显示的周期性活动特点,用正弦函数描述其地震活动规律,并结合时间序列的周期图及其他一些地震活动性分析方法,对该地区未来1~3年地震活动发展趋势和地震强度作了初步预测。
【Abstract】 In this paper,according to the periodically active characteristics shown in the historical earthquake data in this region since 1900,we describe the rule of seismicity with sine function and furthermore make a preliminary forecast of the seismicity intensity and the developing trend in Northeast China till the year of 2008 by using the periodogram of time sequence and other analytical methods.
