Fig. 4

Relative reflection strengths along NS vertical cross section. The locations of cross sections are shown in the lower right-hand side of the figure. Hypocenters of DLFs occurring within 5 km of each plane are plotted as blue stars. Black lines represent active faults. The assumed angle of inclination is shown at the upper left-hand side of each panel. Blue lines show areas in which the number of data points assigned to each grid cell exceeds 10,000. We consider that relative reflection strengths within blue lines are sufficiently accurate. The names of the fault zones [Kyoto Nishiyama, Hanaore, and Biwako Seigan] are putted near each fault zone in the inset map
