【摘要】 对2011年12月1日莎车Ms5.2地震的天体引潮力周期变化过程进行计算,并根据该周期分析了NCEP温度数据资料,提取地震前的异常增温变化图像。结果表明:天体引潮力对处于临界状态的活动断层具有诱发作用;震前温度变化发生明显异常,经历起始增温→异常加强→高峰→衰减→平静的演化过程;出现温度异常位置与震中位置有较好的空间对应关系;NCEP温度异常研究在地震前兆研究中有较好的实用价值。更多还原

【Abstract】 The cycle process of tidal force of celestial body for Shache M_s 5.2 earthquake on Dec.1, 2011 was calculated.According to this cycle,the abnormal temperature increase was analyzed based on NCEP data before the earthquake.The result indicates that tidal force of celestial body has a triggering effect on active fault.The temperature abnormal increase varied with the cycle calculated from changes in tidal force of celestial bodies:initial temperature rise→abnormal increase→reaching peak→attenuation→return to normal.There is a good correspondence between the epicenter and the temperature anomaly.NCEP temperature anomalies have good practical value on earthquake precursors study.更多还原
