Fig. 9From: Development of a detection method for short-term slow slip events using GNSS data and its application to the Nankai subduction zoneRegional characteristics of S-SSEs for 23Â years. a Cumulative number of S-SSEs. b Cumulative slip of S-SSEs. Green lines represent slip contour with an interval of 0.2Â m. c Cumulative duration of S-SSEs. Green lines represent duration contours with an interval of 200Â days. d Average duration of S-SSEs. e Average slip rate of S-SSEs. Note that the grid points experiencing less than five events are shaded in b-dBack to article page
