Fig. 1From: Submarine terraces reveal Late Quaternary tectonic deformation in the intermediate zone between the island shelf and rift zone of the middle part of the Nanseishoto Islands, southwest JapanIndex map of the study area (A, B) and using data from this study (c). Shaded relief maps overlain by contour maps (A and B) use a 500 m mesh DEM (J-EGG500) from the Japanese Coast Guard (JCG), a 1-degree mesh DEM (ETOPO 1) provided by the National Center for Environmental Information (USA), and inland SRTM-3 data provided by the US Geological Survey (USGS). Red lines in B indicate active fault lines identified by the Research Group for Active Faults in Japan (1991), Arai et al. (2015), Goto et al. (2018), and Honza et al. (1977). C-1: 0.65-s-mesh DEM of Sato et al. (2013) and onshore SRTM-3 data provided by the USGS, C-2: 1.44-s-mesh DEM of Yasuhara (2013) and C-1, C-3: 2.03-s-mesh DEM data from the Darwin website of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and C-2, C-4: 2.08-s-mesh DEM produced from the contour lines on the chart of the Japan Hydrographic Association and C-3, C-5: 9.69-s-mesh DEM of the J-EGG500 from JCG and C-4Back to article page
