Fig. 1From: Continuity, segmentation and faulting type of active fault zones of the 2016 Kumamoto earthquake inferred from analyses of a gravity gradient tensorTopography and distribution of the gravity measuring points used in this study. Red lines show the active faults (Nakata and Imaizumi 2002) and the broken red lines show the extended fault lines of the Futagawa fault zone (HERP 2013a). The black dots indicate the gravity measuring points. The magenta and cyan circles represent subsequent seismicity [April 14, 2016, at 21:16 and April 16, 2016, at 14:00 (JST)] after the mainshock and the foreshock, respectively. The yellow star indicates the epicenter of the mainshock and the orange star that of the foreshock. The black triangles indicate the active volcanoesBack to article page
