Figure 7From: Seismic imaging and velocity structure around the JFAST drill site in the Japan Trench: low V p, high V p/V s in the transparent frontal prismOBS data and its tau- p conversion. (a) The vertical component seismograms at OBS JF1 from shots along the line JFS12. The data were band-pass filtered (3 to 12 Hz). Some major phases are indicated in this section. (b) The same seismograms as Figure 7a but in tau-p domain. The envelope of the seismograms in Figure 7a was converted into tau-p domain. Major phases are indicated in the section.Back to article page
