九江地震NCEP异常增温和天体引潮力附加构造应力变化初步研究

利用美国国家环境预测中心NCEP全球再分析资料的温度图像结合天体引潮力附加构造应力,对2005年11月26日江西九江地震进行了分析.分析表明：NCEP温度异常图像可以较好地反映九江地震构造活动时空演变过程;天体引潮力附加构造应力对地应力处于临界状态的活动断层具有明显的诱发作用;预示利用NCEP温度异常图像与天体引潮力附加构造应力结合进行地震短临预测,对大陆少震区也具有良好应用前景.

Using the Astro-tidal-triggering and the NCEP Temperature Increase Abnormal Information to Analyze the Earthquake of Jiujiang

Using the spatial-time fluctuations in the dynamics of temperature data of National Center for Environmental Prediction of American (NCEP) and the additive tectonic stress of astro-tidal-triggering, The earthquke is analyzetl which occurred in Jiujiang of China on Dec.26, 2005. The result shows: the temperature abnormal information of NCEP could reflect the spatial-time evolution procession of earthquake tectonic activity of Jiujiang. The astro-tidal-triggering could trigger earthquake when the terra stress is in critical status. It indicated that these methods can be used to forecast the short-impending earthquake in the region of the mainland where the earthquake is scarce.
