NCEP结合GPS技术在地震分析预测中的应用初探--以日本北海道2003.9.26Ms8.1地震为例

首次试用NCEP(美国国家环境预测中心)全球再分析资料结合GPS(全球定位系统)监测数据对日本2003年9月26日Ms8．1级地震进行了综合分析。结果表明：此新方法能够有效地反映临震地面红外异常增温，增温异常区域与GPS监测到的日本板块运动最大速率部位基本吻合，表明红外增温异常与区域地壳相对加速活动有关，两者结合是一种短期临震前兆探测的较好方法。

Preliminary Study of NCEP Combining GPS Technology in Analysis and Estimate the Earthquake --Take the Earthquake of Japan(Sep 26,2003) for Example

e data of NCEP verification remote sensing over the world and combines with the data of GPS monitors to analyze the earthquake of Japan (Sep 26,2003) is firstly used. The result shows that the new method can effectively reflect the infrared temperature increasing abnormally before short-impending earthquake. The abnormal area is consistent with the movement of the biggest velocity part of tectonic plate that GPS monitors. It proves that infrared temperature increased unusually has something to do with the regional earth's crust accelerate and combing the two methods is a better way to monitor the omen of short-impending earthquake.
