Analyzing the relation between earthquake and structure distortion, main fault belt, crust, upper mantle, ground fracture, hotspring, geotherm, conductance frame, stress state in Guanzhong area is analyzed with earthquake mechanism, isoseismal line, crustal stress measure, fault displacement measure, and simulating test results. Earthquake formation mechanism is discussed with dynamics mechanism in Guanzhong base. There are 3 forces and a good medium environment, which are main reasons caused earthquake happened in Guanzhong area. The first force is NE and NEE level extrusion one which is parallel with long axis of Guanzhong base. The second one is level strain which is vertical with long axis of the base.
