Abstract: Based on M_S≥7 earthquakes data of Philippines in recent 40 years,using methods like commensurable calculation,map of butterfly structure and commensurable structure,this paper analyses M_S≥7 earthquakes activity in the Philippines and its future trends.The result shows that Philippines M_S≥7 earthquakes in 2014,2015 send stronger signals,the future epicenters may be in the northeast of the epicenter of the October 15,2013 Philippines earthquake,about in the north of 9.8°N,in the east of 126.704° E.Philippines M_S≥7 earthquake has a certain relationship with the earth's change of the rotation speed, and the possibility is higher in the deceleration phase,and the longer conversion,the more possible earthquakes happen.It is also found that when solar activity is in the strong active period,sunspots before and after the peak,the probability of an earthquake is very big.Now,Earth rotation is in the deceleration stage,solar activity is in the 24 sunspot cycle which is near the Great Years,so in 2014-2015,the possibility of M_S≥7 earthquakes in Philippines is very big.
