Fig. 6

Distribution of the static stress drop of similar aftershocks (circles) and that of the mainshock (contours). The static stress drop of similar aftershocks (circles) is plotted over the distribution of the static stress drop of the mainshock (at intervals of 2 MPa) as reported by Horikawa (2008). The gray area shows a negative static stress drop. A star shows the location of the hypocenter of the 2007 Noto Hanto earthquake
