Fig. 5
Grid models of accumulative displacements for a only postseismic deformation and b total deformation including postseismic and interseismic movements. Time span of the accumulative displacements is from the 2003 Chengkung earthquake to 2006 Taitung earthquake. Yellow star denotes the epicenter of the Chengkung earthquake. Red lines are the active faults shown in Fig. 1. Figure 5a provides amount of postseismic displacements, which can be used to calculate how much postseismic deformation occurred. Figure 5b shows amount of total displacements after the earthquake, which can be used to justify if the total displacements exceed the tolerance of the reference frame
