Fig. 9From: “N”-shaped Y/X coda spectral ratio observed for in-line-type OBS networks; S-net and ETMC: interpretation based on natural vibration of pressure vesselAverage Y/X amplitude spectral ratio (solid red curves) and logarithmic standard deviation (dotted red curves) at θ = θmax° obtained for six ETMC stations. The θmax and D1max values for each station are written at the top and inside of each subfigure, respectivelyBack to article page
