摘　　要：对2009年7月9日姚安6.0级强震前地震活动、前兆和相关宏观异常进行分析,发现这些异常对该地区6.0级以上强震的预报和研究具有一定的参考价值。In this paper, the seismic activities, precursors and related macroscopic anomalies of earthquake before Yao＇ an Ms 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 Ms≥ 6.0 strong earthquakes in this area.
