摘要
本文从地震孕育背景、前兆异常时空演化的角度,较为系统地回顾分析了2010年6月22日宁夏永宁4.5级地震的前兆异常及宏观异常特征。通过对前兆异常分析,总结了对于此次地震前提出的短临预测依据,可对今后地震预测提供参考。
Based on the earthquake preparation background and spatio-temporal variability,we recall systematically the precursory anomaly and macro-anomaly change characters on the Yongning M4.5 Earthquake on 22 June 2010,Ningxia.Through the analysis of the precursory anomaly and macro-anomaly changes,we summarize the short-and imminent-basics before this earthquake and think that these basics will be useful for future earthquake forecasting.
