In recent years have been demonstrated several methods for earthquake prediction. One of these methods is positive holes (p-holes).this theory is based on thermal anomalies and is one of most powerful theories related to earthquake prediction (Freund, 2003). Thermal anomalies occurred 7 to 14 days prior to earthquakes in areas at about thousands cubic kilometers surroundings earthquake epicenter.

 In this paper based on p-holes theory, in October 14, 2004 Ravar earthquake (ML=5.1), considered thermal anomalies by AVHRR thermal bands (4, 5) data acquired from NOAA satellite in a range of 14 days to earthquake. Findings illustrated that 8 to 4 day prior to earthquake has been occurred perturbations in radiance parameters that these perturbation whit high likelihood related to stress increase surrounding of earthquake epicenter.
