Device and method for locating a microseismic event taking place in a subsurface of the earth. The method includes receiving recorded seismic data S(t, Rc) acquired by a plurality of receivers as a function of time t and a position Rc; receiving a reference signal model SiMo(t, Rc) that corresponds to seismic data recorded by the plurality of receivers if an explosion occurs at an injection point in the subsurface; time correlating the recorded seismic data S(t, Rc) with the signal model SiMo(t, Rc) to determine correlated seismic data DMSS; calculating a detection curve for each of plural cells in a given volume in the subsurface of the earth based on the correlated seismic data DMSS; and determining a seismic location in the volume of the microseismic event based on a largest value of maximums of the detection curves calculated for various points of the given volume in the subsurface.
