Detecting seismic event automatically and accurately is the base of earthquake rapid report. In this paper, a new method of automatic seismic event detection(EGLP) is proposed, which is based on the characteristics of seismic signal such as non-Gaussian, non-linear, plane polarization and STA/LTA method. Appling on Shangdong seismic network's digital seismic wave. It is found that the new method can suppress the Gaussian noise and make seismic signal evidence, improve the accuracy of seismic event detection. |
