In this paper preliminary results of research which are about thermal precursory anomalies are given during geothermal observation and study in the east of liaoning and seismic area Haicheng. Experimental continuous observations of temperature is performed for fixed dril holes of seismic area Haicheng, and observation data are also analysed. On the basis of these data, we discuss possible causes to give rise to thermal anomalies of precursoryness by various data of thermal anomalisms before haicheng earthquake and tangshan earthquake. We are inclined to understand that obvious anomalous increasing temperature of atmosphere is independent of some geothermal process to be usually guessed in crust.
