摘要

文章运用原始形态法对昌黎井数字化水温观测在4次强远震前记录的原始资料进行初步分析。结果表明,强远震前的异常形态特征相近,主要是打破趋势,且幅度明显,认为可能是断层预滑或断裂预扩展产生的,对提高强远震前的异常识别及地震预测有着实际意义。
        Raw data of digital water temperature observation of Changli well before 4 far field strong earthquakes are analyzed in this paper,by using morphological method. The results show that all anomalies,breaking the trend with significantly amplitude,before far field strong earthquakes are of similar morphological characteristics,which may be generated from the fault pre-slip or pre-pre-expansion and has practical significance for improving anomaly identification before earthquakes and earthquake prediction.
