Map showing distribution of the observation points (stations). Circles indicate S-net stations and are colored according to subsystems. Squares show locations of OBPRs deployed from 2008 to 2019. Not all stations were operating simultaneously. Diamonds denote stations in the TM system. Crosses are seafloor benchmarks in the GNSS-Acoustic geodetic survey. Epicenters of tectonic tremors (Nishikawa et al., 2019) are plotted as gray dots. Water depth contours are in 500-m intervals
