摘要
系统分析了１９９７ 年新疆伽师强震群多次中强以上地震前新疆地震窗的短临异常特征，并根据窗口网小震月频度异常对伽师强震群首次６ 级地震（１ 月２１ 日）作出了较好短期预报。同时通过分析阿图什余震窗在其后多次中强地震前出现的小震日频度异常，提取出了阿图什余震窗的异常判据和预报指标。统计检验结果表明。
Before many moderate,strong earthquakes in the 1997 Jiashi strong earthquake swarm,the data of the seismologic windows in Xinjiang showed short term and impending earthquake anomalies.The anomalous features are analyzed systematically in this paper.Based on the monthly microseismic frequency anomaly of the window net,the first M\-S≥6.0 earthquake (Jan.21) was given a better short term prediction.Meanwhile,by analyzing the daily microseismic frequency anomaly of the Atushi aftershock window before later moderate,strong earthquakes,the anomalous criterion and prediction indexes of the Atushi aftershock window are extracted.The statistics and test to them indicate that aftershock window method has better impending earthquake prediction effect.
