Elastic wave forward modeling of simulated micro earthquake

The invention provides the elastic wave forward modeling of simulated micro earthquake. The method comprises the steps that the rock property is analyzed according to the actual data of geological survey; the mode of rock fracture is determined; a moment tensor matrix expressing a micro earthquake source is generated; the geological velocity field model of an explored area is established; under a fluctuation theory, an elastic wave fluctuation equation which is suitable for describing the propagation of a micro earthquake wave field is established; under the fluctuation theory, a micro earthquake elastic wave fluctuation equation is solved to realize micro earthquake wave field propagation simulation; simulation is completed; and multi-component recording of micro earthquake ground and in a well and longitudinal and transverse wave energy radiation patterns are output. According to the elastic wave forward modeling of simulated micro earthquake, a simulation result which is more accurate than a ray theory can
