Maps of central Kyushu Island, Japan, and the Uchinomaki hot spring area. a Locations of the faults (blue lines) and hypocenters of the foreshock and mainshock (yellow stars) and aftershocks (gray dots) of the 2016 Kumamoto earthquake are shown (modified from Tsuji et al. 2017). The dashed line outlines Aso caldera. b Enlarged map around the Uchinomaki hot spring area. c Positions of microtremor arrays (white dots). Purple lines represent open fissures revealed by field observations and interpretations of satellite data (Tsuji et al. 2017). We used the 10-m mesh digital elevation model (DEM) in a, b, and regional map in c published by the Geospatial Information Authority of Japan (http://www.gsi.go.jp/)
