This study attempted to acquire information of tectonic activity in Western China from the data of the land surface temperature (LST) field. Based on the established relationship between heat and strain, analyzed the LST distribution in Western China using the satellite data product MODIS/Terra. The result shows that there are departures of annual changes of LST in some areas, which are associated with activity of some active tectonic zones.  In combination of data of ground temperature at varied depths, seismicity and GPS measurements, the authors checked the information of tectonic activity derived from variations of the LST field, and discussed its implications to the models of regional tectonic deformation.
