| 摘 要： | 应用MODIS遥感数据中反应地表温度的数据波段,对2011年3月11日的日本9.0级地震影响区域进行震前震后的变化检测分析,结果表明,区域范围的温度异常逐月、逐天变化皆较为显著,可为大地震的震情预测提供依据。

LAND SURFACE TEMPERATURE CHANGING BEFORE AND AFTER JAPAN'S M9.0 EARTHQUAKE STUDY BASED ON MODIS DATA |

| Abstract: | Using the land surface temperature data of the MODIS Remote sensing image, we analyzed the differences before and after the 2011 Japan's M9.0 earthquake which is typical for case analysis. Change detection results in the affected area of Japan's earthquake showed that before and after the earthquake the land surface temperature data around the epicenter was changing regularly daily and monthly, and this kind of thermal infrared anomaly before earthquake could be used to predict large earthquake in the future. |
