Fig. 5From: Feasibility study on calculating the Q value of shallow media by using a dense seismic array and a large-volume airgun sourceAmplitude spectra of six stations. The waveform in an 8-s time window starting from the onset of S wave is shown on the left, and the amplitude spectra of six stations is displayed on the right. The waveform of the amplitude spectra in b is indicated in red in aBack to article page
