SS-OCT offers a significant advantage by extending the depth range with only a small loss of sensitivity [ 6– 8].
For the 4 kHz probe, the beam diameter at the output of the CLS was about 8 mm, the transverse resolution at the focal point was 15 μm, the confocal parameter was 260 μm, and the beam diameter at the position apart from the focal point by 2 mm, (half the depth range), was 230 μm.
we use only one iteration of the filter; before processing we scale the depth range by factor of 20, thus reducing the number of slices, and subsequently reducing the processing time.
The failed segment near the SW flank is characterised by low resistivity topsoil in the depth range 0 1.8 m with resistivity value less than 100 Ωm (clay) observed in the geoelectric section which correlates with low resistivity (< 100 Ωm) topsoil in the depth range 0 2 m between station distance 0 60 m observed in the 2-D resistivity structure.
In our implementation of the filter, we have suggested two simplifications: we use only one iteration of the filter; before processing we scale the depth range by factor of 20, thus reducing the number of slices, and subsequently reducing the processing time.
Later, Watanabe et al. extended the depth range by introducing a complex conjugate removal process and achieved a real-time B-scan frame rate of 27.23 fps [ 28].
We note here we consider earthquakes only within the depth range specified by the Experiment committee.
The depth range covered by the synthetic log was focused on the sedimentary part, where permeability indicators were detected, for example between the 890- and 1,280-m 1,280-mFigure 5).
The stable segment of the road pavement is characterised by relatively high resistivity topsoil in the depth range 0 2.5 m with resistivity values greater than 140 Ωm.
The latter is of importance in justifying the aforementioned assumption, since we would like to calculate the depth range influenced by a thermal perturbation associated with the last tectonic event, i.e., uplift at the late Miocene Pliocene.
