Relation between the open crack and the landform. The base map is a slope gradation map made from the 5 m DEM released by the GSI. Yellow and red arrows show fissure and crater, respectively. a Distribution of fissures and craters that formed by past volcanic activities. Fissures a, b, c, g, and h, and craters #1 and #2 correspond to the fissures and craters detected by Kobayashi (2008). b Location of the open crack and deflation sill models estimated by the model inversion. The red line and blue rectangle show the location of the estimated open crack and sill, the parameters of which are listed in Table 3. Crater #3 is the location of craters formed by the 2015 phreatic eruption (Mannen et al. 2015a)
