【摘要】 通过对首都圈及邻近区域的地震资料采用自然正交簇解析方法,分析了中强以上地震前地震活动能量时间因子和能量空间分布异常情况,发现自然正交簇解析的方法能够较好地提取中强震前的地震异常信息,虽然有些异常规律并不十分明显,其物理机制也不是十分明确,但是该方法还是一种有效的、值得探索的地震预测方法。更多还原

【Abstract】 In this paper,using the analytical method of natural orthogonal function expansion,the time factor and spatial distribution of the energy field of seismicity in the Captial Circle and its surrounding area before strong earthquakes are studied.Our study shows that this method is effective in distinguishing the information of seismic anomalies before strong earthquakes.更多还原
