| Abstract: | The seismic background noise of Lianyungang Seismic Station belongs to class Ⅰ noise level by calculation and analysis,and the noise difference between day and night is about 3 dB by analyzing the waveform data of Lianyungang Seismic Station from June to July.The man-made interference of the seismic background noise of Lianyungang Seismic Station is the interference of engineering vehicle for infrastructure,personnel gathering and the vehicle in the scenic spot,and the natural environment interference is mainly caused by strong wind. |
