Fig. 3: Comparison of seismic reflection sections and tremor distribution.
From: Structural barriers control the spatial extent of slow earthquake slip
In each panel, the top panel shows the tremor probability along the survey line, and the bottom panel shows the seismic reflection image along the survey line. The thick solid and dashed lines represent the décollement and the top of the subducting oceanic crust, respectively. The thick red lines represent the frontal thrust. Blue-shaded area indicates a zone of transparent seismic facies interpreted as a low-velocity zone (LVZ). The white stars represent the branching point of the frontal thrust on the décollement. The inset map shows the tremor probability as shown in Fig. 1, and the locations of the branching points are indicated by the white stars. The pink lines represent the locations of the reflection sections, where the thick, solid portions represent the locations of the reflection sections shown here. The complete sections are shown in Supplementary Figs. 2–7. DF deformation front, YDF younger deformation front, ODF older deformation front, ITZ imbricate thrust zone, FTZ frontal thrust zone.
