Using meteorological assimilation data provided by NECP, we analyzed the temporal-spatial variation char- acteristics of temperature on isobaric surface in two months before and after Hualian M6.3 earthquake on Feb. 7 in 2010 basing on per-pixel method. The result showed that there appeared isolated distribution of high-tempera- ture zone in the front-end of Philippine Plate moving to Eurasian Plate in five days before the earthquake. With approaching of Hualian M6. 3 earthquake, the temperature anomaly gradually moved to the sea area between O- kinawa Trough and Ryukyu Trench, and the greatest warming amplitude is as high as 6~C, which coincided with temporal-spatial distribution of thermal anomaly of other earthquakes. It indicated the per-pixel method ap- plied not only to inland earthquakes with great topographic relief variation but also to the oceanic earthquake with island distribution.
