Perspective view of the bathymetry overlaid by the tremor probability is sliced along survey lines A2, B3, and C2. Green solid and magenta dashed lines denote slip and unslipped area during the 2020–2021 episode, which is inferred from the tremor distribution. Roman numerals (i-vi) correspond to the key interpretations summarized in the main text: (i) steep thrust, (ii) less-deformed zone near the younger deformation front, (iii) LVZ above the décollement, (iv) strike-slip faults, (v) rigid prism, and (vi) less-deformed zone behind the subducted ridge. Arrows on top indicate the spatial extent of the 2016 and 2020–2021 episodes. The surface projection of the subducted Paleo–Zenisu ridge (yellow-shaded area) is based on ref. 40 and is reproduced with permission from Elsevier.
