Magnitude differences in USGS body wave magnitude mb and ISC body wave magnitude Mb (1973–2005). Mbmb is shown in the a Sumatra area and b Japan area. Because the magnitude differences are 0.1 interval unit, the magnitude differences are plotted with small perturbations. The horizontal red lines are mean differences during the earlier period until 8500 days. The smoothed surfaces of Mbmb on the plane of mb over the period are shown in c Sumatra area and d Japan area. Contours show an equidistance of 0.1 magnitude unit differences of the smoothed surface, and thin and thick purple show higher magnitudes differences than thin and thick light blue. The horizontal light blue line represents the lowest magnitude of completeness, Mc = 4.7. The vertical dark blue lines show changes of the magnitude difference pattern in the range where plots were highly changed
