Fig. 4.From: High resolution seismic velocity structure around the Yamasaki fault zone of southwest Japan as revealed from travel-time tomographyHorizontal views of the Derivative Weight Sum (DWS) at depths of 2, 5, 7, 10, 12, 15, 17, and 20 km for (a) the V p structure, and (b) the V p /V s structure. The DWS is plotted on a logarithmic scale, where black and white regions indicate high and low DWS values, respectively.Back to article page
