1. A method for identifying a seismic event, the method comprising: detecting a plurality of seismic data signals using a seismic monitoring system, each of the plurality of seismic data signals indicating energy levels; extracting by a processor an extracted portion of each of the plurality of seismic data signals based on a respective maximum energy level among the energy levels indicated by each of the plurality of seismic data signals, the extracted portion of each of the plurality of seismic data signals indicating an energy level, among the energy levels indicated by a respective one of the plurality of seismic data signals, equal to or greater than a selected proportion of the respective maximum energy level of the respective one of the plurality of seismic data signals; comparing the extracted portion of each of the plurality of seismic data signals to a known time pattern corresponding to a seismic event, and determining a correlation between the extracted portion of each of the plurality of seismic data signals and the known time pattern based on the comparing; and identifying the seismic event based on the correlation.
