Fig. 2

A schematic model of subsurface structure of Hakone volcano. Diameter of the caldera is approximately 10 km; however, structure beneath the volcano such as magma chamber and open crack are not to scale. This model is a modified version of previous models (Yukutake et al. 2015; Mannen et al. 2018) based on recent studies (Doke et al. 2018; Kobayashi et al. 2018; Yoshimura et al. 2018; Mannen et al. 2019; Ohba et al. 2019; Yukutake et al. 2019)
