Abstract: In this paper, taken the 31 magnitude equal or greater than 7.0 earthquakes from 1900a to 2014a in the Yellow river basin as an example, the Mars apparent position, opposition and the lunar regression of apparent declination were calculated. The results as following: (1) the lunar regression DEC is one of the main background factors which triggering earthquakes. The Mars opposition is the secondary factors. The earthquake in Yellow River basin is apparently influenced by the Mars opposition. (2) When the DEC great than 20° and less than 22°, then the Yellow river basin comes into the period of none earthquake occuring, especially meeting with the Mars opposition in this range. (3) When the Martian opposition occurs in other basins and the apparent declination of lunar regression doesn't corresponds to the Yellow River basin, then the strong earthquakes will occurred in this region. Therefore, earthquake can be triggered lastly by many astronomical factors aforementioned.
