Abstract: The paper studies the relationship between the earthquake and spatio-temporal changes of the addictive tectonics stress caused by the celestial tide-generating force (ATSCTF) about the M7.3 earthquake of Japan at 38.5°N, 142.8°E, and extracts the abnormal temperature increment before and after the earthquake by using the National Centers for Environmental Prediction (NCEP) data according to the ATSCTF''s time cycle. The analysis reveals that the time when the ATSCTF''s absolute value on P-axis and N-axis reached peak is same to the time of the earthquake''s occurrence, the abnormal temperature increment before the earthquake is obvious and the area of abnormal temperature increment mostly locates to the east of the epicenter, the minimum values’ spatial distribution of the ATSCTF on P-axis and N-axis mostly focused to the east of epicenter on the day earthquake occurred, at the same time, the unbalanced spatial distribution was similar to the abnormal temperature increment distribution, this phenomena testifies the ATSCTF''s inducing effect to the earthquake''s occurrence from another perspective.

As the global energy market undergoes profound changes with price of oil reaching record highs and China emerging as a major force in world energy and global energy geo-politics, a debate on what has been described as ‘China energy threat’ seems to be gaining ground in western strategic circles. However, this is an illusion that is now somewhat exaggerated and overrated. As a matter of fact, the effect of the United States on global energy security affairs is far greater than that of China, and Washington is also not always the defender of the energy security as it claims to be.
