The invention discloses a method for high-resolution determination of seismic event P-wave reverse azimuth and slowness. The working steps of the method are that: supposing that the array is composedof N stations, taking the nearest station from the center of the array as the reference station and setting the station as the origin; the vertical component seismic displacement waveform records of the N stations are read, and instrument response removing and de-mean processing is performed on the records and the same sampling rate is obtained through resampling; the waveform records of all the stations in the step 2 are aligned according to the transmitting array time and the time window is selected; and the selected seismic records are windowed and subjected to Fourier transform so as to obtain the record spectrum, i.e. the observation vector. The method has the beneficial effects that the high-resolution seismic event P-wave reverse azimuth and slowness parameters can be provided by the method in comparison with the conventional station array FK algorithm; and the P-wave reverse azimuth and slowness parameters of the seismic event can be inversed quickly by using the constraint ofthe sparse characteristic of the sources in space distribution.
