【Abstract】 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.更多还原
