Fault traces and lineaments in the southeastern-central NKTZ and to the southeast of the zone. a Distribution of fault traces and lineaments in the study area. Red lines and black lines show fault traces and lineaments detected in this study that are consistent and inconsistent with the distribution of Quaternary fault traces reported by Research Group for Active Faults (1991), respectively. The rectangles indicate the studied Inobuseyama and Kurumijima areas (see Figs. 6 and 10, respectively). b Fault traces and lineament densities in kilometers per unit area (1 km²). The polygon enclosed by the red lines indicates the area covered mainly by the Nohi rhyolite. The 1:25,000-scale topographic map is from the Geospatial Information Authority of Japan
