The invention provides a seismic signal identification method and device. The method comprises the steps that at least one seismic channel is acquired; at least one seismic channel is stacked into thetotal seismic channel; the main seismic signal is determined from the total seismic channel; at least one signal to be identified is determined from the total seismic channel; the similarity of eachsignal to be identified and the main seismic signal is determined; and when the signal to be identified of which the similarity is greater than or equal to the preset threshold exists, the signal to be identified of which the similarity is greater than or equal to the preset threshold acts as the seismic signal. According to the seismic signal identification method and device, the seismic signal can be more accurately identified.
