【Abstract】 In this paper,the seismic activities,precursors and related macroscopic anomalies of earthquake before Yao an M_S 6.0 strong earthquake occurred in July,2009 are analyzed. These include temporal and spatial distribution characteristics of strong earthquake,seismic rhythm and time interval characteristics of the M≥3.0 earthquakes in Chuxiong area,water temperature and water level in Dayao and Nanhua,related earthquake prediction Indexes, and macroscopic anomalies of two reservoirs.These anomalies have certain reference value for the prediction and study of the M_S≥6.0 strong earthquakes in this area.更多还原
