From: Identification of a nascent tectonic boundary in the San-in area, southwest Japan, using a 3D S-wave velocity structure obtained by ambient noise surface wave tomography

Fig. 6

Absolute S-wave velocity values and their perturbation from the velocity average in lateral S-wave velocity slices at 0.5 km and 3 km depth. a, c, e, and g Rayleigh wave results. b, d, f, and h Love wave results. In each panel, black lines show prefecture borders, and depth is shown above the upper left corner. a White and red triangles show the locations of Mt. Daisen and Mt. Sanbe, respectively, the red line shows the Kamakurayama south fault (KSF), the black bold line shows the 2000 western Tottori earthquake fault, and blue lines show other previously recognized faults in this area. c The locations of sections X–X′ and Y–Y′, shown in Fig. 10, are indicated. f The dashed black rectangle indicates a lineament through Shimane to eastern Hiroshima. The results without topography correction are shown in Additional file 1: Figure S1
