A Location map of Miyakejima volcano. Broad blue lines show the plate boundary. PH Philippine Sea Plate, PA Pacific Plate, NA North American Plate. Orange triangles show the location of active volcanoes. Background image is after Google Earth. B Simplified geological map of Miyakejima volcano. Broad black lines show the topographic rim of Kuwanokidaira caldera (KD), Hatchodaira caldera (HD), and the 2000 AD caldera (2k). Dotted line is the buried caldera rim of Kuwanokidaira and Hatchodaira calderas. Pre: edifice of pre-Hatchodaira caldera (older than ~ 2.3 ka). P1: distribution of the deposits of Period 1. P2: the deposits of Period 2 (from seventh to fourteenth century). P3: the deposits of Period 3 (from sixteenth century to present). Distribution of Jinanyama scoria cone and Kamakata lavas are indicated by Jy and Ka, respectively. C Distribution of the representative eruption fissures of Period 1 (yellow), Period 2 (orange) and Period 3 (red). Due to the cover of the younger deposits, not all the eruption fissures are identified
