Abstract：In order to study the formation mechanism of the manila subduction zone earthquakes distribution, based on the latest Moho depth and crustal thickness and other geological and geophysical dates, three typical cross-sections, this paper simulated thermal structure of subduction zones. The results show that ①thermal structure of subduction zone is mainly affected by subduction angle, velocity and geological conditions of the plate itself; ② BB’ and CC’ are warm subduction; ③ When the ocean crust arrive the asthenosphere boundary, the plate temperature rises rapidly, forming dense earthquakes. BB’ have a shallower earthquake because of the smaller subduction angles and velocity. Subducted oceanic crust temperature at the bottom is lower than the top, earthquakes have continued to greater depth.
