| 摘 要： | 总结了丰满台水管仪两个测项在4次≥8级大震前记录的前兆波,对其特征进行初步分析,认为可能是断层预滑或断裂预扩展产生的,可能是大地震孕育过程中的一种反应,对大震的预报有一定的参考意义。通过对前兆波特征的深入研究可以为地震预测提供有力的依据。

| Abstract: | By studying the earthquake precursor wave of 4 M ≥ 8 earthquakes recorded in tilt meter with 2 components in Fengman Seismic station and analyzing its features preliminarily, we have established that such earthquake precursor wave may be caused by pre-sliding or pre-expansion of fault. Hence, the emergence of earthquake precursor wave might be a corresponding response in the earthquake preparation process. A thorough study in earthquake precursor wave might provide a powerful tool to earthquake forecasting. |
