Abstract This paper aims at interpreting the formation of the temperature anomaly of the South China Sea before earthquake. The relationship between the high temperature and the occurrence of oil and gas reserves and gas hydrates is also discussed according to the mechanism of high temperature shown in images. It is found that the temperature increasing probability comes to 64% before earthquake in areas where the oil and gas reserves have been found. It is an indirect method for the exploration of oil and gas resources based on temperature increasing caused by methane emitted from leakage of oil and gas before earthquake. The areas of high temperature shown in the images are mainly distributed in the abyssal zone of Zhujiang River mouth basin, Taixinan (southwest Taiwan) basin, Xisha Islands trough, Bijianan (south Eijia Mountain) basin of the South China Sea, showing probable potentials of oil and gas reserves and gas hydrates.
