Two-dimensional cross-sectional model; the red column is the conduit. A sealing structure is introduced beneath the crater only in Case A (black blocks). In Case C, Region 2 has a higher permeability than the host rock (Region 1). A permeability reduction at PCB (permeability changeable block) is imposed at the time of conduit obstruction
