From: Giant rhyolite lava dome formation after 7.3 ka supereruption at Kikai caldera, SW Japan
A red relief image map of Kikai caldera based on our bathymetry survey. Topography of the unsurveyed and onland areas is drown by using M-7000 digital data of Japan Hydrological Association and digital elevation model of Geospatial Information Authority of Japan (https://fgd.gsi.go.jp/download/menu.php), respectively. Inner and outer caldera rims are shown by solid lines. Several intrusions (yellow) are distributed along the caldera rims. Dredge (yellow diamond), ROV diving (blue diamonds), and scuba diving (yellow triangles) points are also shown. D1, R1 and R2 are sites where photographs in Figs 4 and 6 were taken. This map was generated using MakeRRIM ver.1.1.0”28 that is an Asia Air Survey in-house C program29.
