Lithosphere would expand resulting in the development of tensional faults because of the high local mantle magma pressure caused by the dive of continental plate to another continental plate. Then mantle magma and hydrothermal fluid can go out to the surface along tensional faults, from which rocks are formed by cooling when mantle pressure decrease. Upwelling supercritical fluid would force the left magma into mantle. Supercritical fluid would convert to a mineral substance and fill up faults in upper crust. The middle-lower crust would be filled with supercritical fluid. Because subducted plate blocks mantle heat flow, the lower crust temperature of overlying lithosphere will go down. Then groundwater can get into middle crust. The tensional fault zones temperature in middle-lower crust would decrease because of groundwater vertical convection, which makes supercritical fluid convert into gas/liquid. Sedimentation occurs in faults in lower crust and the faults in middle crust will be worthy of the name of cavity. When surrounding rocks of the cavity are damaged, rocks would fall into cavities and resulting in earthquake. The scale of the earthquake depends on qualities and decline depths of rocks
