Maps showing locations of the study area and MT stations. a Tectonic setting of the Hokkaido region showing the study area. Red triangles denote active volcanoes. b Map of the study area showing simplified local geology and the locations of MT stations. Yellow and blue circles denote MT stations used in 2000–2001 and 2005, respectively. Green diamonds are MT stations used in resistivity modeling by Yamaya et al. (2017). Note that MT data from stations 420 and 450–500 were used in the 3-D inversions of both this study and that of Yamaya et al. (2017). The gray line marks the seismic refraction/wide-angle reflection profile of Iwasaki et al. (2004). The background elevation image was constructed from the ETOPO1 global relief model (Amante and Eakins 2009)
