a Location map of the study area. Yellow lines show the Itoigawa-Shizuoka tectonic line and the Shibata-Koide tectonic line. b Topographic map around the EBFZNP. Gray solid lines (AD) are the gravity survey lines. Line B corresponds to the seismic survey line (Kato et al. 2013). Red solid and red dashed lines indicate precisely located active faults and inferred active faults, respectively (Nakata and Imaizumi 2002)
