Fig. 4From: Source constraints for the 2015 phreatic eruption of Hakone volcano, Japan, based on geological analysis and resistivity structureResistivity range of waters in Owakudani area. The sampling sites are represented in Fig. 2. The surface and mud hell waters suggest relatively higher resistivity (0.7–4 Ωm), whereas waters highly influenced by the new fumarole after the eruption demonstrate lower resistivity (0.03–5 Ωm)Back to article page
