摘要
Using seismic wave data recorded by Hotan, Xinjiang, seismic array, the authors apply F-detection algorithm to identify pP or sP phase on P-wave seismograms of 3 earthquakes, of which the epicentral distances are 22.1°, 6.44° and 39.62°, respectively. The study result indicates that the F-detection algorithm is helpful in relatively accurate identification of pP or sP phase. To verify the validity of F-detection algorithm, the authors use it to analyze the wave data of central distance 22.1° event with additional different level noises. The result indicates that pP or sP phase can still be identified.
