In this paper, land surface temperature variation in the Yilan-Yitong fault zone has been analyzed by using the land surface temperature product of moderateresolution imaging spectroradiometer（MODIS） research group from 2000 to 2011. After removing the stable annual variation component, the temperature residuals were analyzed. The purpose of this study is to find the thermal information related to tectonic activity by temporal and spatial analysis of land  surface temperature observation with the influence of topography, latitude and other interferences being excluded. The result shows a significant continuous temperature decline for the two months at the beginning of 2001 and 2010 in the northern part of Yilan-Yitong fault. Meteorological factors are excluded by analyzing geo-temperature and rainfall data. Based on GPS studies, the Yilan- Yitong fault exhibited remarkable increase of tensile strain rate after the 2011 Tohoku oki earthquake in Japan, and the tensile strain would lead to temperature decline according to experiment result. Therefore, the phenomenon of temperature decrease is presumably caused by the tensile activity of the fault.
