a Estimated aseismic slip rate on the interface between the Amurian plate and the Philippine Sea plate based on the detrended dataset for the period between January 1, 2013, and October 1, 2013, with the unit of cm/year. The white arrow also indicates the estimated aseismic slip. The dashed lines indicate iso-depth contours of the plate interface with an interval of 20 km (Hirose et al. 2008). Thin solid lines indicate prefectural boundaries in Japan. b October 1, 2013–May 1, 2014. c May 1, 2014–October 1, 2014. d October 1, 2014–April 1, 2015. e April 1, 2015—July 1, 2015. f July 1, 2015—February 1, 2016. g February 1, 2016–April 10, 2016. h Total slip between January 1, 2013, and April 10, 2016, with the unit of cm. The moment magnitudes of the three areas (1)–(3) separated by blue dashed lines are computed as the Bungo, northern Miyazaki, and southern Miyazaki slow slips in Fig. 6 and Additional file 6. The numbers of earthquakes within 5 km from these three segments are indicated in Additional file 6. ip Estimated 1σ error for the periods corresponding to (ah). The contour interval is (i) 4 mm/year, (jo) 1 cm/year, (p) 1 cm
