Overview of SSEs and earthquakes in the southernmost Ryukyu subduction zone from 1991 to 2018. The black rectangle represents the previously studied fault plane of the 2002 March 31 Mw 7.1 Hualien offshore earthquake (Lee et al. 2009). The dotted contours show isodepths of the subducting plate interface from Wu et al. (2009). The cumulative slip of SSEs derived from Chen et al. (2018) and the seismicity derived from the relocated earthquake catalog (Wu et al. 2008) are colored. The dotted rectangles represent the seismogenic structures on the plate interface. ISZ: interplate seismogenic zone (Kao 1998). The horizontal displacements (black arrows) represent the interseismic velocity on the onshore GNSS stations (green triangles) from 2007 to 2016. The horizontal displacements have corrected the effects from the 2002 Mw 7.1 earthquake, three local earthquakes (EQ1 to EQ3 with focal mechanisms), and SSEs. EQ1 to EQ3: the 2002 May 15 Mw 6.0, the 2004 May 1 Mw 5.8, and the 2005 March 7 Mw 5.9 doublet earthquakes. The yellow triangle denotes the reference S01R station
